The all stainless steel construction of the Fig. A72 valve makes it suitable for a wide range of applications.The valve is single seated, piston controlled and spring regulated.
The hydraulically balanced spindle enables the valve to maintain a constant upstream (relieving) pressure regardless of downstream pressure fluctuations.
It is an ideal valve to employ where a direct spring loaded type of valve is too insensitive to pressure flow variations.
Protects systems from overpressure. Maintains constant pressure in a system by discharging excess product to atmosphere or container. Reduces cavitation or other damage to pumps by bypassing back to suction at a given pressure. For water, oil, gas or chemical services.
