The No. 210 & 213 series MGM Relief Valves are designed for the protection of piping and equipment from over-pressure conditions. They are available for any predetermined pressure from 50 to 1500 psig and will automatically reseat after discharge. Valves in this series feature American Standard 1/8” or 1/4” male and female pipe threads to mate with new or existing fittings or equipment.

Other features of the MGM No. 210 & 213 series relief valves are seat discs made of Viton which provide a “bubble tight “ seal. Pipe Away Adapters are available for the direct connection of vent piping when required. Outage tubes (dip tubes) have been incorporated into the inlet end of the No. 213 series valves.

NOTE: Each relief mechanism is set to the required pressure and sealed before leaving the MGM factory. When ordering the customer should state the model number and pressure desired.

Recommended for all cold water system installations - to protect against damage to piping and pressure tanks. PRV"s are set at 75 PSI or 100 PSI. PRV"s have a plus/minus 15% setting accuracy

Note: Merrill pressure relief valves may not reseat themselves after pressure relief. Manual disassembly and reseating of the valve may be required. Repeated opening of a pressure relief valve is beyond intended use and voids warranty

*Note: ALL PRV valves are field adjustable - by removing the cap and turning internal disk down to increase pressure. Field adjustment of valve voids warranty.

Warning: ALL PRV, SSPRV, and PRVNL valves must be set a minimum of 15 PSI above the typical high of the water system pressure, so valve chatter or rapid open and close will not occur. Valve chatter can cause the failure of the valve and voids warranty.

Regulate air, gas, and liquid pressure on food, beverage, and pharmaceutical lines with these valves—they’re 3-A certified to meet sanitary design standards. Attach them to your line to reduce a high, variable inlet pressure to a lower, stable outlet pressure.

Twist the T-handle on top of the valve to adjust the outlet pressure. When the valve is closed, a seal on the outlet prevents leaks and helps maintain consistent pressure. These valves meet ANSI/FCI 70-2 Class III, which means a maximum of 0.1% of fluid, gas, or air can escape while they are fully closed. The spring and valve mechanism are sealed behind the diaphragm, so contaminants can’t enter. Both the diaphragm and seals hold up to water, detergents, and chemicals. They’re also FDA compliant for direct contact with food.

Made of 316 stainless steel, these valves won’t corrode from frequent washdowns with harsh cleaners. They connect to your line with quick-clamp sanitary fittings, also known as tri-clamp connections, which are easier to remove and sanitize than threaded connections. The polished interior is extremely smooth, so there’s nowhere for bacteria to hide. They’re also self-draining, so liquids drain completely and don’t contaminate your line. Keep these valves open during clean-in-place (CIP) cycles with a locking pin.

Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination. They’re often used in research sample systems, emission monitoring systems, and chromatography. Valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Outlet fittings are Swagelok® for a leak-free seal around hard metal tubing in high-pressure lines. Also known as instrumentation fittings, Swagelok® fittings are compatible with Parker A-Lok, Gyrolok, Bilok, and Tylok fittings. Valves come with a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.

Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.

Two-stage valves progressively reduce pressure over two steps for more consistent outlet pressure at all times. They’re often used in applications that require a constant outlet pressure regardless of the tank level.

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.

An external nut lets you adjust the pressure without disassembling the valve. These 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.

This pressure control valve is used for very relief valve control applications such as maintaining bypassing excessive pressures from various types of process equipment, and wherever maximum pressures cannot be exceeded in a process or piping system. Because of the needle nose piston, this valve is also used for relieving high pressures at very low flows. The 303 stainless steel valve can be used for non-corrosive or mildly corrosive fluids. Use only clean filtered or strained liquids or gases to remove debris or other solid matter that might cause internal clogging or improper operation of this precision machined valve. Install a filter or strainer with a fine wire mesh (at least #20 mesh) before the inlet of the back pressure valve. High-pressure in-line strainer fittings, basket strainers, and fine wire mesh filtes can be purchased from Stra-Val.
