SB10/SB11 Back Pressure/Relief Valves

Clean Liquids BPR Valves

The SB10/11 Series is very sensitive to pressure changes and requires low overpressure to fully open. It is designed for clean fluids only.

• Size: 3/8”-2”

• Ends:  True Union Socket, Threaded or
  ChemFlareTM* Spigot** Bodies with Plain, Socket,
  Threaded or Flanged ends

• Diaphragm: Teflon® Bonded EPDM

• Seals: EPDM, FPM (Viton®)

SB12 Back Pressure/Relief Valves

The SB12 Series has a built-in check valve function, desirable for dosing applications. It is not so sensitive as to open with every pulsation from a metering pump.

• Sizes: 3/8" - 4"
• Ends: True Union Socket, Threaded or
  ChemFlareTM*
  Spigot** Bodies with Plain, Socket,
  Threaded or Flanged ends
• Diaphragm: Teflon® Bonded EPDM
• Seals:EPDM, FPM (Viton®)

SB17 Back Pressure/Relief Valves

Has two functions. As a back pressure valve, installed in-line downstream of a pump, the back pressure below the metering pump is maintained. When installed in the branch of a tee it is a pressure relief valve. The valve stays closed until inlet pressure reaches the set pressure which is adjusted by turning the spring tensioning bolt. The “Mini” SB17 size relief valves offer high performance in a compact package.

• Size: 1/4" - 3/8"
• Ends: Socket, Threaded or ChemFlareTM*
• Diaphragm: Teflon® Bonded EPDM
• Seals: EPDM, FPM (Viton®)

SB50 Back Pressure/Relief Valves

Maintains a set downstream pressure independent of higher variable upstream pressures. As downstream pressure increases reaching the set pressure, the valve closes. It opens as soon as the downstream pressure decreases below set pressure.

• Sizes: 3/8" - 3"
• Ends: True Union Socket, Threaded or
  ChemFlareTM*
  Spigot** Bodies with Plain, Socket,
  Threaded or Flanged ends
• Diaphragm: Teflon® Bonded EPDM
• Seals:EPDM, FPM (Viton®)

Allow gases to escape from unpressurized pipe lines. It must be installed vertically at the highest point in the piping system with the “Air” arrow up. As the unpressurized air vents, liquid rises to the float (an inverted cup), which lifts the float up against the seat, holding liquid pressure. The float will not release until the pressure on the inlet side of the valve is equal to the outlet pressure of the valve (normally atmospheric).

• Sizes: 1/2" - 3"
• Ends: Socket, threaded, Flanged
• Seals: Seals: EPDM, FPM (Viton®)

Inexpensive pressure gauges, or any other pressure instrument to be used in corrosive services. The upper chamber (gauge side) is filled with a stable fluid such as glycol or glycerine*. A diaphragm separates it from the lower chamber which receives the media under pressure.

• Process Connection Sizes: 1/4" or 1/2" NPT
• Instrument Connection Sizes: 1/4" or 1/2" NPT
• Diaphragm: Teflon

High Capacity Ball Valve

True large port 6" ball valve manufactured in PVC, polypropylene and PVDF. Most other 6" valves often are 4" with ends increased to 6". HC Series offers an unobstructed full port which allows passage of mechanical pipe cleaners or “pigs”. Applications include unfiltered sea water and sewage lines. It is also suitable for mild slurries and vacuum lines.

• Sizes: 6" and 8"
• End Connections: Socket, Flanged or Butt
• Seat: Teflon® PTFE
• Seals: EPDM, FPM(Viton®)

Large Size Compact Ball Valves

The 6" size is a full port alternative to a 4" ball valve with ends increased to 6". Seats are Teflon® for long life and low stem torques. The 4" size is also available with Hypalon® seats, superior on sustained vacuum applications and many slurries.

• Sizes:4" and 6"
• End Connections: Flanged
• Seats: Teflon® PTFE, Hypalon® (CSM)*
• Seals: FPM (Viton®), EPDM

Pneumatically Actuated Diaphragm Valve

Type 710

Plastic piston actuator designed for long cycling life and corrosion resistance. Compared to a 1/2" pneumatically actuated ball valve it is a fraction of the size and cost.

• Ends: True Union Socket, Threaded or
  ChemFlareTM*
  Spigot** Bodies with Plain, Socket,
  Threaded or Flanged ends

  or Double Acting

Manual Diaphragm Valve

 Type 720

Large variety of body materials and end connections. It is much smaller than other 1/2" diaphgram valves.

• Ends: True Union Socket, Threaded
  ChemFlareTM* or Spigot** Bodies
• Diaphragm: EPDM, FPM (Viton®) or Teflon®

Pneumatically Actuated Diaphragm Valve

Type 730

This valve offers long cycling life, high pressure resistance and a size range 1/2" to 4". Being a diaphragm valve, it is available for sanitary or slurry applications. With a Teflon® diaphragm, it has corrosion resistance superior to ball or butterfly valves. This becomes an economical control valve when a positioner is added.

The Type 730 is part of the 700 Series of diaphragm valves. They feature interchangeable bodies, diaphragms and actuators. Modular construction minimizes spare parts requirements. All major parts are solid plastic – corrosion resistant and light weight to minimize stress on plastic piping
