D/R Series actuators are linear spring diaphragm pneumatic actuators designed for reliable operation of rising stem control valves. The D/R is a simple and rugged unit available in a combination of case sizes, strokes and springs to satisfy a wide range of applications. For valves requiring longer travel and higher thrusts, the A46 and A47 are available. The A46 is a direct-acting actuator, while the A47 is a reverse-acting model. For detailed specifications, please refer to the product bulletin D/R Series -1

Velocity control trim is suitable for compressible and incompressible fluids and provides many advantages that result in improved performance, reduced maintenance and system simplification. This advanced design “velocity control” trim prevents the generation of noise and or cavitation at the source, eliminating the need for supplementary devices such as diffusers and silencers, and the related expense. As implied in the name, the trim is based on velocity control principles. The tortuous fluid path is formed by the number of concentric cages, radial flow paths and the number of axial flow changes along the milled cavities. The cylinders are firmly connected by vacuum brazing, eliminating external leakage, or short circuiting, while permitting sufficient inter-stage clearance flow. As fluid passes through each passage, velocity is “controlled”, followed by a correspondingly “controlled” pressure reduction. For detailed specifications, please refer to the product bulletin 500M.

General Service Control Valves Our standard offering includes several styles of globe and angle valve styles. The G110 Series provides cage-guided valves through 16” and ANSI Class 600. For higher pressure ratings, we offer the V510 and V520 valves for coverage through ANSI Class 2500. For services requiring top-guided trims, we offer the G120 with threaded-in seat ring and the G130 with ‘quick change trim’. For larger dirty services, our V800 Series delivers rugged top and bottom guiding.

Series V800/V801 Top and Bottom Guided Double Seated Globe Valve

1” through 12” ANSI Class 150, 300, 600, 900,1500

The V800/801 Series is a double-seated, top and bottom guided globe-style valve with screwed-in seat rings. This style of valve is extremely useful in erosive (dirty) fluids and systems where high flow rates are required. This valve style may be ordered as air to open or air to close without a change in actuator.
