Choosing The Right Valve

CONSIDERATIONS:

• Will the valve be used with single or double-acting cylinder?
• Will the valve be mounted on the pump, away from the pump or directly into the hydraulic lines?
• Will the valve be manually operated or is remote control preferred?
• Is independent control of multiple cylinders, or hydraulic tools preferred?
• What directional control and pressure control valve functions are needed for the application?

Basic valve types include manually operated, air or solenoid operated and pilot operated. Special application valves for pre-stressing and post-tensioning are also offered.

IN-LINE HYDRAULIC VALVES

Load Lowering Valve - Provides precision metering for controlled return of the cylinder pistion.

Sequence Valve - Used when a cylinder in a multiple cylinder application must advance before any other.

Pressure Reducing Valve - Permits independent pressure control to two or more clamping systems operated by a single power source.

Shut-off Valve - For fine metering of hydraulic oil. Several may be used to control multiple single-acting cylinders.

Check Valve - Permits flow of hydraulic oil in one direction only.

Pressure Relief Valve - Used at remote location in a hydraulic circuit where maximum pressure requirements are less than the setting of the basic overload valve in the pump. Protects a hydraulic system against over pressurization.

Metering Valve - Restricts surges by restricting flow to a certain level; when flow subsides, valve reopens automatically. For systems using large cylinders or extended lengths of hose.

Pressure Regulator Valve - Permits external adjustment of operating pressures at various values below the internal relief valve setting of the pump.
