BTS/BFS Pilot Operated Pressure Sustaining Valve (CI/DI/BZ/304SS/316SS)
Elite model BTS/BFS uses a MFV (multi-function valve) which is directly fitted with a pressure sustaining valve pilot and is used primarily for water. Unlike conventional pilot operated valves which have a complex external pilot valve tubing assembly, this valve does not have any external piping or tubing, saving cost and simplifying installation.
It is available in BTS threaded version 1½”→ 2” (Cv’s 48-75) and BFS flanged version in 2”-14” (Cv’s 75-3,000) and the choice of materials for the main valve are cast or ductile iron with bronze trim, bronze, 304ss or 316ss. Diaphragm and seat material can be either NBR or Viton and the pilot valve can be bronze or stainless steel.
Valve has either threaded ends (1½”→ 2”) or flanged (1/2”-6”) which can be drilled to suit Ansi 150# or AS Table D/E.
