Parker R Series balanced port

The Parker Sporlan Type R expansion valve features balanced port design, an external adjustment assembly and the replaceable element assembly.

Parker’s R Series Relief Valves are designed such that when the upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve.

Pressures range from 10 PSI (0.7 BAR) to 6,000 PSI (413.7 BAR).
