- The Model FTV Tri-Service Valve operates automatically and silently. Line pressure of approximately 1/4 psi will open the disc. The spring closes the disc as the line flow approaches zero in order to prevent flow reversal & water hammer. The flow through the valve can be adjusted from bubble tight shut off to full flow by the threaded rising stem.
