Parker Autoclave's Y Series yoke valves are a non-rotating rising stem design, built to operate safely and reliably to 50,000 psi (3447 bar). Yoke valves are extra heavy-duty, plant grade valves for industrial and severe service applications.

Parker Autoclave's Y Series yoke valves are a non-rotating rising stem design, working pressures to 50,000 psi (3447 bar). These yoke valves are extra heavy duty, plant grade instrument valves for industrial and severe service applications. Yoke valves feature low closing torque for ease of operation. The tubing size is 9/16” to 1”. Tubing connections utilize the Parker Autoclave cone and thread design. Standard high pressure needle valves with PTFE packing may be operated from 0°F (-17.8°C) to 450°F (232°C). High temperature packing is available for service 600°F (316°C). These high pressure needle valves have adjustable packing below the threads to eliminate the media from contacting the power threads, and causing galling during actuation

Along with their many features these valves provide dependable and trouble free service in wide variety of applications.

Markets:
- Oil and Gas
- Petrochemical
- Chemical
- Power
