Standard W60 Adapter:The ‘standard’ adaptor is used on all models of short and long stroke W60 Series valves. Machined from SS 316L bar with a thick cross-section, the adaptor adds strength to the valve body and provides alignment for the stem. The outer perimeter seals to the valve body with an o-ring that is located forward to the product zone to minimize crevices. The product stem passes through the adaptor and is sealed to the adaptor with an o-ring. A Teflon® bearing guides the stem and takes up the mechanical loading imparted by hydraulic forces. This increases the service life of the stem seal. Adaptors are made in 1"-6" (25mm -152mm) sizes.

W80 Adapter: This adaptor is used to convert a ‘standard’ W60 series valve to a W80. The outer perimeter seals to the valve body with an o-ring that is located forward to the product zone to minimize crevices. The product stem passes through the adaptor and is sealed in the upper part and the lower part of the adaptor with o-rings. The space between the o-rings is flushed with a suitable liquid or steam. The Teflon® bearing is located in the flushed chamber. Adaptors are made in 1"-6" (25mm - 152mm) sizes. For vacuum-rated, extended shelf-life (ESL) applications, the W80A adaptor adds steam trace to the adapter-to-valve body connection.

Wiping Stem Seal Adapter: For high-risk and hard to clean product applications, the wiping stem seal fills the gap between the product zone and the traditional o-ring stem seal. The adaptor is a two-piece design to allow easy inspection or replacement of the wiping stem seal. The outer perimeter seals to the valve body with an o-ring that is located forward to the product zone to minimize crevices. A Teflon® bearing is used to guide and support the valve stem.

Alter the set pressure to suit your application. These valves begin opening at the set pressure and fully open at about 10% over the set pressure. Tighten the locknut to prevent accidental changes in set pressure. Valves should not be used in applications that require the valve to close completely below the set pressure.

Change set pressure without guesswork—the adjustment screw is marked in 25 psi increments for making pressure adjustments without a gauge. These valves are commonly used with thermal-expansion protection systems and low-capacity pumps. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure.

A finely threaded adjustment screw lets you make precise set pressure adjustments. These valves are for use with diesel fuel, fuel oil, gasoline, and kerosene. They begin opening at the set pressure and fully open at about 10% over the set pressure.

Valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

Designed to meet 3-A sanitary standards, these valves regulate liquid, gas, and air pressure in hygienic zones of food and beverage plants. They’re often used at the end of pipelines on processing and sanitizing equipment. Made of 316 stainless steel, they won"t corrode from frequent washdowns with harsh cleaners. With an extremely smooth interior that self-drains, bacteria won"t have time or space to grow. The spring and internal valve mechanisms are sealed off behind the diaphragm, which also prevents contamination. They connect with quick-clamp fittings, so disassembling to clean your line takes little time.

These valves obstruct flow to maintain sufficient operating pressure in your system. If the system pressure exceeds the set pressure, they exhaust through the outlet. They meet ANSI/FCI 70-2 Class III standards for shut-off valves, meaning a maximum of 0.1% of fluid, gas, or air will escape through the outlet when they’re closed. An integrated T-handle lets you set the outlet pressure without additional tools. The diaphragm and seal resist repeated exposure to water, and they’re FDA compliant for direct contact with food.

To set the pressure, unscrew the cap and turn the adjustment screw. Valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and fully close when the system pressure is restored below the set pressure.

Pressure relief valves, also referred to as safety relief valves, are triggered to open at a designated pressure and expel fluid until the pressure reduces to an acceptable level. In its operating condition, this pressure relief valve is typically closed until upstream pressures increase to a predetermined set pressure. When that set pressure is reached, the valve opens, and continues to open wider, enabling additional flow as the pressure increases. The valve starts to close again when the upstream pressure drops to a few PSI below the set pressure.

A 100-percent pure PTFE Valve Body and Valve Plug are used in the manufacture of the iPolymer Pressure Relief Valve (PRV).
