Parker has a wide range of hydraulic valves for a variety of mobile and industrial applications. But which one is right for you? Let’s explore the range…
Parker Hannifin are one of the world’s most prominent hydraulic manufacturers of motion and control technologies. Their range of valves are used in hydraulic, pneumatic, instrumentation, refrigeration and aerospace applications. And moreover, they come in a range of types and configurations. For instance they can be manual, motor actuated, solenoid air operated and electrically actuated. Moreover, mounting configurations can be sub-based, in-line or manifold.
The range of Parker valves comprises:
The range includes: load and motor control valves, logic element valves, solenoid coils and valve drivers. In addition the range includes: hydraulic line bodies, manifolds and cavities, manual valves, solenoid valves and hydraulic slip-in cartridge valves.
These valves are unidirectional flow devices used primarily in hydraulic systems to eliminate potential damage caused by fluid back pressure. There are one- and two-stage poppets available with pilot ratios of 1 : 5 and 1 : 40 to suit different operating conditions.
Parker offers the industry’s largest selection of hydraulic directional control valves. Their main target markets include: machine tools,
power generation, metal forming, compacting and baling, materials testing, ground support and primary metals processing. Moreover, Parker provides solenoid controlled, as well as manually operated valves controlled by levers, cams, air or oil pilot. These valves are some of industry’s most adaptable, with a large number of coil termination options available. To sum up, the full range includes: hydraulic pilot operated directional control valves and solenoid operated directional control valves. As well as: hydraulic CAM operated directional control valves, Exectrol directional control valves and hydraulic Lo-Torque directional control valves.
Parker’s hydraulic flow control valves are known throughout the industry for their performance and reliability. Flow control valves are used in a range of applications, such as: conveyors, food processing machines and material handling equipment. In essence, they ensure velocity by guaranteeing consistent flow regardless of load. Flow control valves come in a variety of materials including stainless steel, brass and carbon steel.
Parker manufactures hydraulic mobile valves for virtually every mobile equipment application, from simple on/off functions to precise motion control. These include bankable control valves, motion control valves, remote controllers, directional valves and manifold mounted directional and proportional valves.
Parker offers hydraulic needle valves for speed controls on hydraulic and pneumatic systems, where a reverse flow check is not needed. Moreover, they provide excellent control and a reliable shutoff in a very small envelope. A two-step needle allows fine adjustment at low flow by using the first three turns of the adjusting knob. Subsequently, the next three turns open the valve to full flow, and also provide standard throttling adjustments.
These valves include pressure control valves, pressure reducing valves and pressure relief valves.
Parker proportional valves employ powerful voice-coil valve technology, which allows higher flows from smaller valves. These proportional valves offer extremely high response up to 300 Hz, and are offered with or without on-board control electronics.
Parker offers a complete line of hydraulic seat valves designed for directional control functions. They enable individual hydraulic solutions for nominal flow up due to a large variety of poppets, springs and covers, including shuttle valves, stroke limiters, solenoid valves and position control.
Parker’s sequence valves are used to control the sequence of operation of two or more hydraulic actuators. The sequence valve pressure is set higher than the first actuator operation pressure. Once the first actuator has completed its cycle, the sequence valve opens, allowing the second actuator to move. Parker’s line of pilot-operated sequence valves include a series of internally piloted, externally drained valves and a series of externally piloted, internally vented valves.
