    Product Description

  • SERVICE RECOMMENDATIONS: The Model FTV-S & FTV-A Tri-Service Valve is primarily designed for installation in pump discharge piping where it functions as a spring loaded silent check valve, flow control valve and shut off valve.
  • OPERATION: 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.
  • FEATURES: The unique convertible body design permits the valve to be changed on site from the straight to the angle configuration. Flow measurement (where an approximate indication is acceptable) is obtained by flow measuring ports on each side of the valve seat. Pressure differential is easily recorded using differential pressure measurement devices. If precision accuracy is required, we recommend that a Gruvlok® Circuit Balancing Valve be installed downstream from the FTV valve.

  • Three functions, one valve — 1. Spring-closure design, 2. Non-slam check valve, 3. Flow throttling valve
  • Reduced field installation and material cost
  • Stainless steel spring
  • High-strength resin seat EPDM for 8" and larger
  • Anti-rotation lugs on the inlet and outlet. These lugs, combined with the Gruvlok 7401 Rigidlok Coupling or the Gruvlok flange adapter provides for a ridged rotation free installation
  • Flow measurement and pump throttling capabilities
  • Temperature measurement capability
  • Spring-closure design check valve prevents gravity or reverse circulation when pump is not operating
  • Bonnet “O” Ring can be replaced under full system pressure by back seating of valve stem
  • Suitable for maximum working pressure to 375 psi (26 bar) and temperatures to 230°F. (110°C).
  • Valve seat can be changed in the field without use of special tools
  • Low pressure drop due to “Y” pattern valve design
  • Valve Cv designed to ASHRAE flow recommendations for quiet system operation
  • Drip-tight shut off valve smoke development rating of 50 or less
