Withstand more than six times the inlet pressure of standard pressure-regulating valves. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have a 303 stainless steel body for corrosion resistance in harsh environments.

Often used in wet conditions and harsh environments, these valves have a 316 stainless steel body for excellent corrosion resistance. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection. They automatically reduce a high, variable inlet pressure to a lower, stable output pressure. Adjust the outlet pressure within the range. Valves are no-bleed style, so they keep process media contained within the valve.

Often used on dispensers, humidifiers, and fountains, these valves have a 316 stainless steel body that can stand up to deionized water and corrosive conditions. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have a low-profile body to fit in tight spots. All have a gauge port.

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. They also have an internal strainer to trap debris. Union fittings on both ends of the valves disassemble for easy valve installation and removal. All of these valves meet Canadian safety standards for pressure-reducing valves. Some also meet American and international plumbing safety and performance standards.

Stainless steel valves resist corrosion better than brass valves.

To regulate inlet pressures up to 6,000 psi in wet conditions and harsh environments, these valves have a 316 stainless steel body for exceptional corrosion resistance. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have threads below the adjustment knob and come with a panel-mount nut. All have two gauge ports. They are no-bleed style, so they keep the process gases contained in the valve.

Commonly used for oxygen service and other high-purity applications, these valves come cleaned and bagged to prevent contamination. All automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have threads below the adjustment knob and come with a panel-mount nut. They can also be surface mounted. All have two gauge ports. Body is 316 stainless steel for exceptional corrosion resistance. Valves are no-bleed style, so they keep process gases contained in the valve.

Maintain contaminant-free standards in clean room environments. These valves come cleaned and bagged to Fed. Spec. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection. They automatically reduce a high, variable inlet pressure to a lower, stable output pressure. Valves have threads below the adjustment knob and come with a panel-mount nut. Adjust the outlet pressure within the range.

Gauge ports let you attach a pressure gauge.

Relieving valves exhaust when the downstream pressure exceeds the set pressure.

Nonrelieving valves do not exhaust excess downstream pressure.

Regulate steam pressure in wet environments and harsh conditions with these valves that have a 316 stainless steel body for exceptional corrosion resistance. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

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 close when the system pressure is restored below the set pressure.

316 stainless steel valves are more corrosion resistant than iron valves.
