Technical Information Fig No. A72

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.
