Data Sheet

Clamping Action

Applying fluid pressure to the A port advances the plunger. Spring return.

Mounting & Fluid Supply

Several possible mounting methods: 1) insert four socket-head cap screws from the plunger end, through the four counterbored holes parallel to the plunger; 2) insert four socket-head cap screws from the bottom end, through the four counterbored holes parallel to the plunger; 3) insert two socket-head cap screws through the two broad-side holes perpendicular to the plunger. Method 3 requires that the Block Cylinder be backed up for pressures over 2300 psi by a rectangular strip or dowel pins with a height at least 1/3 of the B dimension.

1/4" BSPP port (two for double-acting clamps). Larger sizes have 1/2" BSPP ports. Do not use NPT fittings.

Optional Viton Seals

For high-temperature applications (212° to 300° F), we offer Viton seals in all sizes. Viton seals have a slightly shorter service life. Please contact factory for more information.
