Haskel 27741-3 Relief Valve

Features & Benefits:

• Haskel Regulating Relief Valves were originally developed in response to the need for accurate regulation of high pressure at low flow without the “chatter” often encountered with valves of this size. They are differential area poppet design with a high ratio between seal and seat area for smooth control, repeatability and low dead-band between the crack and re-seat pressures.
• The configuration of these valves also makes the control settings virtually unaffected by the downstream outlet pressure. This enables the valves to also be used for back pressure control (upstream pressure controller) or as a sequence (priority pressure) valve.
• Materials of Construction options provide selections for most liquids, including plain water, plus most industrial gases, including pure Oxygen. NOTE: Nylon insert seat models are recommended for all gas applications below 10,000 psig.
