The Cla-Val Model 81-12 Check Valve is a hydraulically operated

No-Slam Check Valve. This valve opens when the pressure at the

inlet exceeds the discharge psudden opening surges. When a

pressure reversal occurs the higher downstream pressure is applied

to the cover chamber through the control tube lines, and the valve

closes drip tight.

This valve is ideally suited for use where a positive shutoff is required.

The rubber disc assures tight sealing even if the fluid contains grit or

other small-size particles. The simple packless design insures

reliable operation and freedom from leaks.
