Clippard Modular 3-Way Valve R-311

The R-311 is a 3-way, spring-return, fully ported pilot valve with four pilot inputs, designed to reduce piping and space requirements by consolidating multiple valve functions. It operates with a minimum pilot pressure of 40 psig, handles working pressures from 0 to 150 psig, and functions within a temperature range of 32 to 180°F. The valve provides snap action with micro gap construction to prevent blow-by and allows speed control at exhaust. It can be configured as normally-open, normally-closed, selector, or diverter, and supports 2-way operation by plugging exhaust ports. Any single pilot actuates the valve; all four pilots must be depowered to return it to rest. The valve is physically designed for modular mounting with indicator guidance.
