Threaded Body (Cartridge Type)

FEATURES: Allows operating a single clamp, or group of clamps, at a lower pressure than the rest of the fixture. Can be used to finely adjust the clamping force of selected components while keeping others at full pressure. Great new design can be used on pallet fixtures disconnected from a power source, since no return line is needed for operation. Zero-leakage poppet design. The threaded-body version shown here is used for cartridge-type manifold mounting. Also available with standard fittings for use with exposed fluid lines, and a manifold-mounted version for mounting on flat surfaces.
OPERATION: To set up initially, turn the adjustment screw on top until the desired downstream pressure is achieved. During normal operation, Pressure-Reducing Valve automatically shuts off downstream flow when system pressure reaches the set pressure. As long as the system remains connected to the power source, the valve will reopen if additional fluid is required to maintain downstream pressure.
THREADED-BODY MANIFOLD MOUNTING: Carefully follow hole-preparation instructions in the drawings. Fluid passages must be drilled exactly as shown in the drawings. Screw valve into fixture up to the body hex. Mount in any position, horizontal or vertical. Do not use NPT fittings.
DESIGN CONSIDERATIONS: When using this valve in series with other valves such as Clamping Valves, Sequence Valves, and Flow-Control Valves, the Pressure-Reducing Valve must be the one closest to the reduced-pressure clamps. When a Pressure-Reducing Valve is used in an uncoupled system, no regulation of downstream pressure is possible after disconnection, so we strongly recommend adding a Pressure-Relief Valve to guard against unwanted pressure increases caused by temperature increases, etc. (must be added to the downstream side). |
