Check & Relief Valves

A valve is a device that regulates, directs or controls the flow of a fluid by
opening, closing, or partially obstructing various passageways.

Valves are technically valves fittings, but are usually discussed as a separate category.

Spec.

  • Working Pressure : 6,000 psig
  • Up to 204℃ (400℉)
  • Designed to stop uncontrolled release of system media
  • DK-Lok 1/4 to 1/2 in. OD
  • Pipe thread 1/8 to 1/2 in.

Brief Description

  • Designed to stop uncontrolled realease of system fluid on downstream line rupture.
  • Stainless steel construction
  • DK-Lok and Pipe End connections up to 1/2 in.

V61

Working Pressure up to 400 psig (28 bar)

Spec.

  • Cracking Pressure : 0.5 to 150 psig
  • -65 to 400℉ (-54 to 204℃) Differ from material selection
  • Pipe thread 1/8 to 1 in.

Brief Description

  • Precise cracking pressure with high reliability.
  • Keeping the sealing to 95~98% of Set Pressure at least.
  • Reliable Reseal performance.
  • Tamper proof design.

V63

Spec.

  • Working Pressure : 300 psig
  • Cracking Pressure : 10 to 225 psig
  • -18 to 400℉ (-28 to 204℃)
  • Stainless Steel with FKM seals
  • DK-Lok 1/4 to 1/2 in. OD
  • Pipe thread 1/4 to 1/2 in.

Brief Description

  • Install the valve between the pump outlet as close as possible, and any shut-off device in the discharge line. The preferable mounting position is vertical with the adjusting cap at the top.
  • By-passes the system fluid to porevent instrument or sensitive gauge in the system from excess pressure.
  • When the inlet pressure overcomes the set spring pressure on th poppet, the poppet lifts off the valve seat,allowing flow to pbypass and thereby balance the system pressure.
