In-line Mounted Pressure-Reducing Valve

The in-line mounted pressure-reducing valve allows operating a single clamp, or group of clamps, at a lower pressure than the rest of the fixture. It 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, with zero-leakage poppet design.

The in-line mounted pressure-reducing valve is used for in-line mounting with standard fittings and exposed fluid lines. The valve is also available in a manifold-mounted version for mounting on flat surfaces, and a threaded-body version for cartridge-type manifold mounting.

To set up initially, it needs to be turned the adjustment screw on top until the desired downstream pressure is achieved. During normal operation, the 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.

It should be mounted with standard fittings, and mounted in-line. Fasten valve to fixture using a 5/16 or M8 cap screw if desired. The valve can be mounted in any position, horizontal or vertical, with two 1/4″ BSPP ports.

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. Furthermore, it must be added to the downstream side.
