For Single-Acting Systems
Use individual clamping valves to clamp several workpieces independently with a single power source. 3-way clamping valves are used to control single-acting clamps. These high-quality valves have a zero-leakage poppet design, with a built-in check valve. Extremely compact. Available either with a mounting base (for installation with standard 1/4" BSPP fittings and exposed fluid lines) or without a base (for manifold mounting using the O-ring ports underneath the valve).
The hydraulic-pilot-operated valve shown here is controlled by a pilot hydraulic line, for use in automated systems. Valve is normally in "clamped" position until pilot hydraulic pressure is applied to unclamp.
Mounting with Standard Fittings:
To use standard fittings, order clamping valve with mounting base (base has three 1/4" BSPP ports). Fasten valve to fixture using the four tapped mounting holes underneath the base. Mount in any position, horizontal or vertical.
For manifold mounting, order clamping valve without mounting base (use the three O-ring ports underneath the valve). Mounting holes and manifold passages must be drilled exactly as shown in the drawings. Fasten valve to fixture using the four mounting screws furnished.
Clamping valve has three ports:
P = Pressure into valve from power source
R = Return from valve to power source
A = Flow from valve to clamps
Port connections and flow directions must be exactly as shown on the drawings; otherwise the valve will not function correctly. Use only with clean, approved hydraulic fluid (CLR-2-FL or equivalent). Fluid must be kept clean (10 micron or better nominal filtration). Do not use NPT fittings.
