81-02 & 681-02Check Valve

[81-02 & 681-02]

The Cla-Val Model 81-02 and 681-02 Check Valves are hydraulically operated No-Slam Check Valve with dual speed controls.  These valves open when the pressure at the inlet exceeds the discharge pressure. A gradual rate of opening prevents sudden 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.

These valves are 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.

  • Simple Proven Design
