Parker Autoclave Engineers, now part of the Instrumentation Products Division of Parker Hannifin, combines high pressure industry knowledge, manufacturing expertise, and technological innovation to offer a broad range of products and services to our customers across a wide range of industries. Our goal is to design, produce and deliver products, systems and solutions that matter… while consistently exceeding customer expectations.
Parker Autoclave Engineers was always the right decision for High Pressure, now that we are with Parker – It’s the ONLY decision you need to make.
Needle Valves
Parker Autoclave Engineers needle valves deliver reliable, leak‑tight shutoff and precise flow control for demanding high‑pressure applications. Built with a non‑rotating rising stem and metal‑to‑metal seating, they ensure long service life and smooth operation even under extreme pressures ranging from 15,000 psi to over 100,000 psi, depending on the series. Available in multiple body patterns and connection types—including SpeedBite, Quick Set, and cone‑and‑thread—they are constructed primarily from 316 stainless steel for durability across harsh temperatures and media.
Ball Valves
Parker Autoclave Engineers ball valves are engineered for reliable shut‑off and flow control in demanding high‑pressure environments. Available in 2‑way, 3‑way, 4‑way, and double block‑and‑bleed configurations, these manually operated valves support working pressures up to 20,000 psi and feature an integral one‑piece trunnion‑mounted ball and stem that eliminates shear failure found in two‑piece designs. Their 316 stainless‑steel construction, re‑torqueable seat glands, and low‑friction, pressure‑assisted stem seal ensure long service life, smooth actuation, and leak‑tight performance across a wide range of media and temperatures.
Valve Actuators
Parker Autoclave Engineers valve actuators provide safe, reliable remote operation for low‑, medium‑, and high‑pressure Autoclave valves, with models supporting pressures up to 150,000 psi. These piston‑ or diaphragm‑type pneumatic actuators are available in multiple duty ratings and configurations—air‑to‑open (ATO), air‑to‑close (ATC), or dual‑acting—to suit shutoff, control, and fail‑safe requirements. They enable remote on‑off or automatic process control without routing high‑pressure lines to operator panels, improving safety and reducing system complexity. Options also include outdoor‑service designs, corrosion‑resistant construction, and compatibility with limit switches or explosion‑proof installations.
Fittings and Tubing
Parker Autoclave Engineers fittings and tubing are engineered for safe, leak‑tight performance in low‑, medium‑, and high‑pressure systems, with pressure ratings ranging from 15,000 psi up to 150,000 psi depending on the series. The range includes SpeedBite single‑ferrule compression fittings for low‑pressure applications, coned‑and‑threaded medium‑pressure connections up to 20,000 psi, and high‑pressure cone‑and‑thread fittings and tubing designed for extreme environments. Manufactured from cold‑worked 316 stainless steel (with optional exotic alloys), these fittings and tubes provide excellent flow capacity, broad temperature resistance, vibration‑resistant options, and complete traceability markings for critical applications.
Adapters and Couplings
Parker Autoclave Engineers adapters and couplings provide reliable, leak‑tight connection solutions for low‑, medium‑, and high‑pressure systems, supporting working pressures up to 150,000 psi depending on the series. The range includes male/female, female/female, and male/male adapters, as well as JIC, bulkhead, SAE O‑ring, reducer, and Quick Set (QSS) medium‑pressure options, allowing easy transitions between different sizes and connection types. All components are precision‑machined from cold‑worked 316 stainless steel (with other alloys available) and are designed to integrate seamlessly with Autoclave fittings, tubing, and valves for demanding industrial applications.
Relief Valves
Parker Autoclave Engineers relief valves are designed to provide reliable, controlled pressure relief in high‑performance gas and liquid systems. The product line includes metal‑seat RVP valves, engineered for extreme‑pressure and cryogenic service with set pressures reaching up to 75,000 psi, and soft‑seat RVS valves, which offer bubble‑tight sealing and excellent repeatability for applications where zero leakage is essential. These valves are built from 316 stainless steel for durability and are available with a range of medium‑, high‑, and ultra‑high‑pressure cone‑and‑thread or NPT inlet connections, allowing seamless integration into demanding Autoclave system architectures.
Accessories
Parker Autoclave Engineers accessories provide essential safety and measurement components for high‑pressure systems, supporting low‑, medium‑, and high‑pressure ranges. The range includes universal safety heads and rupture discs, offering dependable over‑pressure protection with ratings from as low as 90 psi up to 110,000 psi, depending on the series. These units feature 316 stainless‑steel construction, interchangeable hold‑down rings, and compatibility with Autoclave valves, fittings, and tubing for seamless system integration. Additional accessories—such as pressure gauges, thermocouples, and snubbers—further enhance monitoring and operational reliability within demanding industrial environments.
