Compatibility & Interchange:

  • Stucchi VEP-P VEP-HD Series, DNP PST4 FSI Series, Voswinkel FT Series, Parker FET-Series, and Holmbury HFT Series
Features:

  • Two-stage valving to protect critical sealing components during pressurized connection & disconnection.
  • Posi-Lock valve system secures valving during surge-flow conditions to prevent high-velocity damage.
  • No-spill, flush face valve minimizes air inclusion during connection and spillage during disconnection.
  • Threaded design eliminates premature wear or brinelling commonly found with locking ball designs when subjected to high impulse pressures.
Construction:

  • Machined components are manufactured using solid steel bar stock.
  • Stainless steel retaining rings and springs maximize corrosion resistance and extend service life.
  • Steel componentry is plated using ROHS Compliant Zinc Nickel for superior corrosion resistance.
Seal Components:

  • Plugs have Nitrile-energized PTFE valve seals, with a temperature range of -40°F to 250°F (-40C° to 121°C).
  • 3 8 plugs have molded polyurethane valve seals, with a temperature range of -65°F to 212°F (-54°C to 100°C).
  • 3 8 to 3 4 valve stems have molded acetal seals, with a temperature range of -65°F to 212°F (-54°C to 100°C).
  • 1 to 2 valve stems have molded polyurethane seals, with a temperature range of -65°F to 212°F (-54°C to 100°C).
  • Ancillary coupler and plug seals are Nitrile with a temperature range of -40°F to 250°F (-40C° to 121°C).
  • TPC-ET anti-extrusion ring protects main coupling valve seal from dynamic impulse pressure damage.
How It Works:

  • Prior to connecting, thoroughly clean all mating surfaces and threads on both halves, the pull the coupler sleeve forward.
  • To initiate the connection, align the coupler and plug, pushing turning the coupler sleeve towards the plug while engaging the threads. Keep the mating halves aligned during the connection process.
  • Allow the threads to pull the coupler onto the plug, do not push the coupler onto the plug.
  • The first phase of the connection should be threaded by hand, without the use of tools. Please note the connection sleeve may seize when dirt and debris accumulate in the
    threads – wipe away debris with a cloth, compressed air or a brush.

  • The second phase of the connection may require a wrench if the pressure is higher than anticipated.
  • Continue to thread the coupler sleeve onto the plug until the end of the sleeve meets the plug body.
  • To disconnect, use a wrench to break the coupler sleeve free and keep the mating halves aligned during the disconnection process.
