Novatech manufactures well-service pump valves and valve seats for upstream oil and gas applications. The company produces a variety of proprietary valves and valve seats for high-pressure applications such as frac, cement and mud pumps used in unconventional upstream oil and gas operations.

Weir chief executive Keith Cochrane says, “Novatech is a respected brand in the U.S. upstream oil and gas markets, with strong market share in the frac consumables market. This deal enables Weir to broaden our aftermarket expendable product portfolio in this fast-growing sector, where increasing operating intensities require equipment and components to be more regularly replaced and serviced. With the recent acquisition of Seaboard, this strengthens further Weir"s presence in the North American unconventional oil and gas markets and builds a larger upstream product range to offer the developing international shale markets.”

Novatech president, chairman and CEO Starr L. Pitzer Jr., says, “We have worked with Weir"s upstream business as a supplier for a number of years and have come to know the company well and admire the way they operate. Through joining the Group, I believe that Weir"s global sales and service networks will enable the business to grow, not only in North America, but also by taking Novatech products to international customers.”

The Weir Group PLC has agreed to acquire Novatech LLC, a US manufacturer of well service pump valves and valve seats for upstream oil and gas applications, for $176 million (£113 million) in cash.

Based in Dallas, Texas, Novatech is a family-owned business producing a wide variety of proprietary valves and valve seats for high pressure applications such as frac, cement and mud pumps used in unconventional upstream oil and gas operations.

Novatech"s range of durable valves expands Weir"s offering in the fast-growing frac pump consumables markets and significantly enhances its frac pump aftermarket portfolio.

Nova-Tech offers a wide variety of parts to keep your chemical metering pumps in operation. Some of these parts include gaskets, washers, valves, tubing and much more.

Novatech"s machining cells consist of two turning centers equipped with automated gantry loaders. This view shows the original cell that was installed in 2001.

Oil wells use lots of pumps. At almost every step in drilling or operating an oil well, pumps are needed to get various materials in and out of the ground. All of these pumps require numerous valves to control the flow of these materials, many of which are highly abrasive or corrosive. As a result, these valves and the seats they mate with wear out and need to be replaced. Novatech Corporation is in the business of manufacturing these replacement components.

This 19-person shop in Dallas, Texas, was making many of these parts before it became a pump valve company with its own product line. Novatech started out as a job shop, with precision turning as one of its specialties.

Because pumps come in many sizes and types requiring many different sizes of valves and seats to match each pumps capacity, pump manufacturers have to supply a wide variety of replacement parts. These companies were looking for job shops that could produce the pump valve components that need to be replaced frequently. These parts consist largely of axisymmetric shapes, so lathe work is a main part of their production. Because Novatech was experienced at turning, the shop was a good choice for machining these valves.

The company eventually expanded to become a job shop supplier for several pump manufacturers. It began making components for both "mud" pumps used in oil well drilling along with components for well service pumps used to keep an oil well operating. In the meantime, the company continued to do other job shop work, such as defense-related contracts.

The 1990s saw many changes in the oilfield industry. There was widespread consolidation among the oilfield equipment dealers and distributors, leaving many of the independent equipment sellers with gaps in their valve product lines. A number of these sellers turned to Novatech to fill the gap.

Mr. Pitzer realized that his shop could manufacture the most popular valve types very efficiently and be highly responsive to the independent sellers serving oil wells in the field. Novatech was in the right position to make and market its own line of pump valves. Yet Mr. Pitzer didn"t want the shop to lose its heart and soul of a job shop. The shop would need all of its job shop flexibility, creativity and constant focus on efficiency to succeed in its valve business.

Two, he needed to preserve as much flexibility as possible. Given the wide variety of valves and seats that would comprise Novatech"s emerging product line, producing small batches (200 to 300 pieces) would best meet customer orders without creating excess inventory. More important, batches in this range matched the number of pieces that the heat treater could carburize at one time. At this batch size, the heat treater could provide the best turnaround time and lowest cost per piece.

The automatic gantry systems consist of a chain-driven carrousel with 25 stations, a vertical arm that raises and lowers the gripper, and a crossbeam that carries the arm back and forth between the machine and the carrousel. The double-sided gripper is designed to grasp and manipulate the workpiece. The construction of these systems is modular, allowing the loaders at Novatech to be configured for the specific machine tools in its cells. Because the machines face each other, the loaders are configured in right- and left-handed versions.

Simplicity is a key value in automation. It makes automation easy to understand and the benefits easy to see. Simplicity keeps costs down. "Automatic loading gives us the best cost-to-benefit ratio," Mr. Pitzer says. "More automation would give us diminishing returns." On a practical level, simplicity contributes to flexibility. Novatech"s gantry loaders do not require customized grippers or pallet fixtures. Changeover is quick. There is less chance of setup error.

Automation does not necessarily mean untended operation. For Novatech, the value of automation is in enhancing the productivity of the machine and the operator. The shop does not operate the cells in the untended mode. The goal for automation is to match the output of operator-tended shifts with production requirements. "We could run one more carrousel full of parts at the end of the day if we wanted to, but that hasn"t been necessary," Mr. Pitzer says. The automatic loaders allow the operator to act as cell supervisor, taking care of duties without interrupting production. Many of these activities could be automated, but at considerable expense and complexity. The efficiency of the machines would not increase significantly from additional automation, notes Mr. Pitzer. "So why do it?" he asks.

With any automation, attention to details is important.Chip control is a good example. Novatech experimented with various turning insert grades and styles to find those that provided the most reliable chipbreaking function. Avoiding long, stringy chips is critical because resulting "bird"s nests" can interfere with the gripper or the chuck. Details about the chuck jaws proved to be important. The shop installed the more expensive one-piece quick-change chuck jaws because they had fewer places for chips to get caught on. For certain parts, the corresponding chuck jaws have been modified for better flow of compressed air during the chip clearing cycle. Coolant-fed toolholders are also used wherever possible. Coolant gets to the right place even if the regular coolant nozzles are not positioned optimally. Finally, attention to details requires good communication. For example, all setup notes and reminders are stored as text lines in the part program. That way, the operator does not need paperwork on a daily basis.

Automation is only one part of the productivity picture. Novatech continually looks for every opportunity to reduce cycle time and production costs. For example, the company originally used one forging to produce three different valves. This approach reduced the cost of the forge tooling. As quantities increased, it became more cost effective to design separate forgings for each valve so that the forging was nearer to net shape. The new forgings used less material and required less machining. These savings more than compensated for the cost of producing new tooling.

Partnering with the heat treater has also resulted in savings. With the promise of substantial business from Novatech, the heat treater invested in a larger capacity furnace. This allows Novatech to flex batch sizes more liberally without creating a bottleneck.

Novatech also studies product design for ways to improve product quality or reduce costs. For example, many valve bodies require a urethane seal around the OD. The company has developed and patented a technique for molding this seal directly to the valve body, streamlining the process of valve assembly.
