Williams Modulator Valve

Description: The WM607 Series consists of three-way, panel mounted regulating valves with a variety of output ranges. When a WM607 valve's control handle is applied, the valve opens to regulate pressure delivery to the outlet in proportion to the handle's position. As the handle is returned to neutral, air pressure at the valve's outlet is released through the exhaust port. The WM607 features a friction adjustment which restricts or allows free movement of the handle. Important: When friction adjustment screws are loosened to provide minimum handle friction, the operator must hold the handle in the applied position or it will automatically return to neutral.

  • Maximum supply pressure: 200 psi
