Pressure Reducing Valves

Our Products / Valves / Pressure Reducing Valves
  • Model REF Pressure Reducing Valve (316SS, flanged)

  • Elite model REF is a 316ss self acting pressure reducing valve suitable for fluids, air and steam.

    It is available in ½” → 6” (Cv’s from 2.4-250)and the main materials are 316ss with NBR or Viton diaphragm and seals. Valve has flanged ends which can be drilled to suit Ansi 150# or AS Table D/E.

    Maximum inlet pressure-2500 kpa (362 psi)
    Maximum temp- 100°C or 180°C for steam
    Reduced pressure ranges – 100-600 kpa; 400-1,000 kpa; 800-1300 kpa

    * Options: All 316ss adjusting bolt/locknut, pressure gauge



  • WRAS Approved Pressure Reducing Valves (316SS, flanged or threaded)

  • The Elite model RET (threaded) and REF (flanged) pressure reducing valves are now available in an alternative version to our stocked RET/REF valves that have WRAS Approval. This means that all non-metallic parts in contact with the water are intended for human consumption with regard to their effect on the quality of the water.

    The valves are available in ½” → 6” (Cv’s from 2.4-250)and the main materials are 316ss with EPDM diaphragm and seals (our standard valve comes with viton or NBR seals). The valves have either threaded BSP ends or flanged ends which can be drilled to suit Ansi 150# or AS Table D/E.

    Maximum inlet pressure-2500 kpa (362 psi)
    Maximum temp -15°C or 85°C
    Reduced pressure ranges -100-600 kpa; 400-1,000 kpa; 800-1300 kpa



  • Model 5350 DR Bronze Pressure Reducing Valve (with pressure indicator)

  • Caleffi model 5350 is a self acting bronze pressure reducing valve suitable for water. It can be set prior to installation as it has an adjustment knob with a pressure setting indicator. It is available in ½” → 2” and the main materials are DR brass body, NBR diaphragm and seat. A ¼” gauge port is standard and allows a pressure gauge to be fitted directly to the valve. Male unions are supplied as standard.

    Maximum inlet pressure-2500 kpa (362 psi)
    Maximum temp- 60°C
    Reduced pressure range – 100-600 kpa



  • BTR/BFR Pilot Operated Pressure Reducing Valve (CI/DI/BZ/304SS/316SS)

  • Elite model BTR/BFR uses a MFV (multi-function valve) body which is directly fitted with a pressure reducing 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.
    BTR threaded version 1½”→ 2” (Cv’s 48-75)
    BFR flanged version in 2”-14” (Cv’s 75-3,000)

    Materials (main valve) – cast or ductile iron with bronze trim, bronze, 304ss or 316ss. Diaphragm/seat material-NBR or Viton
    Pilot valve – bronze or stainless steel (matches main body material).
    Connection- threaded ends (1½”→ 2”) o/ flanged (1/2”-6”) to suit Ansi 150# or AS D/E.
    Maximum inlet pressure-2500 kpa (362 psi) ..higher pressures by request
    Maximum temp- 80°C
    Reduced pressure ranges – 100-700 kpa; 400-1,200 kpa

    * Options: Pressure gauge, high pressure pilot



  • MK68G Pressure Reducer

  • MK68G is a globe style pressure reducing valve that offers high capacity, accurate regulation and easy servicing (bottom entry design makes it easy to clean or repair). It is available with hard seat (Class IV shut-off) or soft seat (class VI) and applications where the differential pressures do not exceed 300 psi (21 bar). Suitable for water, oil, gas, steam & chemicals.

    Maximum inlet pressure- BZ/DI/WCB/316SS (2,100 kpa)
    Maximum temp- 93°C Buna plug & diaphragm; 177°C Viton plug & diaphragm; 260°C metal seat & SS diaphragm

    Reduced pressure ranges: ranges between 14 kpa-1,100 kpa

    * Options: Low flow trim in all sizes, threaded BSPT, BSPP, NPT or Flanged ends
