The Model 100-01 is the basic valve used in nearly all Cla-Val automatic control valves. It is the valve of choice for system applications requiring remote control, pressure regulation, solenoid operation, rate of flow control, liquid level control or check valve operation.
This valve meets the Drinking Water System Components – Health Effects Standard. Cla-Val Model 100-01 also meets the requirements for lead content in drinking water products, encompassing the requirements in California AB1953 and Vermont 9 VSA Chapter 63, Subsection 1C.
The Cla-Val Model 81-01 and 681-01 Check Valve are hydraulically operated No-Slam Check Valves. Both 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.
The Cla-Val Model 81-02/681-02 Check Valve is a hydraulically operated No-Slam Check Valve with dual speed controls. This valve opens 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.
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 backless design ensures reliable operation and freedom from leaks.
