Series/Model Information

Parker R Series Relief Valves are unique since they offer both a low pressure valve line (RL4) and a higher pressure valve line (RH4). They are both designed such that when the upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve. Flow through the valve increases proportionately to the increase in upstream pressure. These relief valves work from 1-25 psig crack pressure systems up to 5,000-6,000 psig crack pressure systems. The highly visible color coded labels on the valves indicate the associated crack pressure spring included in the valve.

Interchange Disclaimer

Parker guarantees that all A-LOK® fittings (including A-LOK® ended valves) are of equal quality to and will perform as well as the Swagelok fitting. Parker guarantees that the A-LOK® fittings are completely interchangeable with all sizes of the Swagelok fittings and individual components of the A-LOK® fittings can be intermixed with the components of the Swagelok fitting including the new and old rear ferrule. In fact, since 1984, thousands of customers have successfully used the A-LOK® fittings in conjunction with the Swagelok fitting.
