High Pressure Needle Valves

Parker Autoclave Engineers high pressure series offer a diverse line of needle valves from 30,000 psi, 40,000 psi, 60,000 psi, to 150,000 psi (10345 bar).
This wide selection of valves includes many features from various flows and pressures to a full range of tubing sizes for all design requirements.
Tubing sizes from 1/4″ to 1″.
Maximum flow areas for valves in high-pressure applications.
Non-rotating stem prevents stem/seat galling..
Engineered and designed packing for reliable sealing.
Metal-to-metal seating for longer seat life and excellent corrosion resistance.
Vee or regulating tip stem.
Available in up to five body patterns.

RVS Series Relief Valves

Parker Autoclave Engineers relief valves provide reliable venting of gases for set pressures from 1,500 psi (103 bar) to 20,000 psi (1378 bar).
The soft seat design provides bubble tight sealing, repeatable pop-off, and re-seat.
These precision valves are designed for pressure gas systems, where zero leakage is critical.
Relief valves designed to open as a function of increasing system pressure.
Orifice sizes are based on valve pressure ranges./li>
Higher cycle life then metal seat valves.
Constructed of 316 SS with selected components made of anti-galling stainless material.
Temperature range from 32°F (0°C) to 400°F (204°C).
Repeatable reset pressure.
Dependable shut-off.
Fewer parts, ease of maintenance.
CE Mark Option.
