Product Description
The Enardo 860 and 960 Series spring-loaded
pressure/vacuum relief valves are designed to handle
higher pressure settings than standard dead weight-
loaded valves.The Enardo 860 Series is used for pipe-
away aplications while Enardo 960 Series is used for
vent-to-atmosphere applications. Fisher spring-loaded
line are designed for pressures up to 15 psig for tanks
with higher maximum allowable working pressures.
With proper installation, usage and preventative
maintenance, the Enardo 860 and 960 Series can
supply many years of pressure/vacuum relief with
continuous sealing abilities that exceed the most
stringent industry standards (1 SCFH at 90% set
point per valve). Spring-loaded pressure/vacuum
relief valves have the option of weight-loaded pallets
in either the vacuum or pressure portion of the valve.
The following is the list of the available spring-loaded
pressure/vacuum relief valve models. See Figure 4.
