Which valve used in hydraulics?

The various types of pressure control valves used in hydraulic systems include relief valves, reducing valves, sequence valves, counterbalance valves, and unloading valves.

How does a hydraulic valve work?

A hydraulic solenoid valve is a solenoid controlled directional valve used in a hydraulic system for opening, closing or changing the direction of flow of the liquid. The valve operates with a solenoid, which is an electric coil wound around a ferromagnetic core at its center.

How many types of hydraulic valves are there?

Hydraulic valves are subdivided into three main categories: directional control valves, pressure control valves and flow control valves. All valves operate a different function in the hydraulic system.

Which DC valve is mostly used in hydraulic system?

The most common directional control valve is a 4/3-way valve, which means the valve has four working ports and three spool positions. The 2-way directional control valve is the simplest directional control valve that has two ports called inlet and outlet.

What are two types of spool valves?

What is a Spool Valve? – Types, Configurations, Applications

  • Types of Spool Valves. Rotary Spool Valve. Sliding Spool Valve.
  • Construction of Spool Valve.
  • Two-position Directional Control Valves.
  • Three-position Directional Control Valves. Closed Center Valve. Open Center Valve. Tandem Center Valve. Float Center Valve.

How do you identify a hydraulic spool valve?

The Cross computer stock number is stamped in the shaded area on the handle end of the valve body on recent valves. On older valves, the Z casting number is on the back which would tell you which series, but individual functions would have to be described.

What is a control valve in a hydraulic system?

Directional Control Valves are the most commonly used valve in a hydraulic system. Control valves direct the flow of hydraulic fluid from the pump to the actuators or other sections of the hydraulic circuit. Control valves are returned to their neutral state with a spring or held in each position with a detent mechanism.

What is an actuator or operator of a hydraulic valve?

The valve part that drives these flow control components is known as the actuator or operator of the valve. These hydraulic valves can present proper timing or sequencing of the valve position modifications needing to control the hydraulic systems or circuits.

Are our hydraulic products just for excavators?

Our Hydraulic products are not just for excavators. We are in all Heavy types of Industrial Equipment. Supplying the heavy equipment market for over 60 years our Hydraulic Motors, Control Valves and Pumps are widely adopted in Construction, and Heavy Industrial Equipment.

How do you use a 4 way hydraulic valve?

As a 2-position, 4-way valve, it is commonly used to extend and retract a double-acting hydraulic cylinder. As a single-solenoid valve, it will remain in its home position until shifted electrically, returning to home when the power is removed.
