• Large relief capacity in a compact size.
• Lightweight aluminum construction with resilient seat.
The RV01A1N Pop Off Relief Valve is designed to protect against excessive pressure buildup in a pneumatic circuit or system.
With the relief
valve mounted in a reservoir or system, the force of system pressure at
(A) is offset by the force of spring
(C) acting on poppet seat
(B). At pressures lower than the setting, the poppet seat
(B) is held against the body at
(A) effecting a seal. As pressure approaches set point, the poppet begins to vent until set point is reached, at which time the poppet seat
(B) lifts off the body at
(A) allowing the excess pressure to vent to atmosphere at
(F). When the excess pressure has been vented, the spring
(C) acts on the poppet seat
(B) forcing it to seat on the body at
(A), sealing off the flow of air.
