Control steam line pressure with ±1 psi accuracy. 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 cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline. They meet ANSI Class IV for tight shut-off (max. leakage rate of 0.01%). Install 1/4 NPT male pipe (not included) between the control valve and your downstream steam line.
Repair kits (sold separately) include replacement seals, diaphragm, spring, and spring assembly.

Commonly used as bypass lines after centrifugal, reciprocating, and rotary pumps, these valves obstruct flow to maintain sufficient operating pressure in your system. If the system pressure exceeds the set pressure, they exhaust through the threaded relief port. Adjust the set pressure within the range. Valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. Attach a drain line to the threaded relief port for remote discharge. Valves have a cast iron body to absorb vibration for reduced noise and wear in your pipeline.

When input pressure varies, use these valves to maintain a consistent pressure. They are often placed after a directional-control valve and before an actuator, such as a cylinder. They have an indicator/gauge port for the inlet and one for the outlet so you can monitor that output pressure remains steady.

Transfer dry material from storage containers into air-powered conveyors and other pressurized systems. As the rotor’s eight vanes turn, the pockets between the vanes fill with material from the inlet and then dispense material through the outlet. Controlled by a built-in electric motor, this movement delivers bulk material in a controlled manner while maintaining pressure differential between the inlet and outlet. The rectangular flanges have standard bolt holes, so these feeders fit into most air-powered systems. Included neoprene gaskets are sized to fit the flanges to form a tight seal. To calculate the fixed displacement rate needed for your application, divide your material movement (lbs./hr.) by product density (lbs./cu. ft.).
