How do I hook up a hydraulic valve?

How Do I Hook Up A Hydraulic Valve? To extend cylinder, pull handle away from valve. When handle is released, the valve spring centers to neutral stopping cylinder. Neutral: Oil circulates from the pump through the valve and back to the reservoir. Work ports are blocked.

What are the hook-ups on valve accessories for?

Valve accessories are hooked up to achieve the required function of the valve assembly. At SAMSON, we have already implemented over 500 different hook-ups that have proven reliable in field use.

How does a lock-up valve work?

Regardless of the positioner‘s signal and the solenoid valve‘s position, the lock-up valve causes the actuator to remain in its last position as soon as the supply pressure falls below a certain limit. The opening and closing action is accelerated by the volume booster, which boosts the positioner‘s control signal accordingly.

Do you offer control engineering for the entire valve assembly?

In addition to the wide variety of high-quality products in our program, we also offer control engineering for the entire valve assembly. You can benefit from our expertise.

How do you connect valves in series?

Open center or through center valves need to be connected in series using power beyond porting. Power Beyond allows unused flow to power multiple valve sets downstream. Power beyond also allows the designer to choose which valve sections are more important than another. In a hydraulic system, there can be multiple operator locations.

How do you use a neutral valve on a hydraulic pump?

Neutral: Oil circulates from the pump through the valve and back to the reservoir. Work ports are blocked. To retract cylinder, push handle toward valve. When handle is released, valve spring centers to neutral.

How do you extend and retract a hydraulic cylinder?

To extend cylinder, pull handle away from valve. When handle is released, the valve spring centers to neutral stopping cylinder. Neutral: Oil circulates from the pump through the valve and back to the reservoir. Work ports are blocked. To retract cylinder, push handle toward valve. When handle is released, valve spring centers to neutral.

Can a directional control valve be connected to an existing valve?

If the existing directional control valve has an alternative tank port, this allows the tank line from the additional valve to be connected to tank via the existing valve (Figures 1 & 2). Figure 1. Simplified line drawing showing pressure and tank galleries of a directional control valve (DCV) in open center arrangement. Figure 2.

What are the parts of a control valve?

Regardless of type, all valves have the following basic parts: the body, bonnet, trim (internal elements), actuator, and packing. The basic parts of a valve are illustrated in Figure 1. Control Valves mainly have Two parts: 1) Actuator Part. 2) Body Part for easy understanding.

How is the a control valve and actuator assembly tested?

A control valve and actuator assembly is tested on a bench, not under actual operating conditions. To meet leakage criteria, the actuator must be assembled to provide seating force beyond that required to stroke the valves fully open (or closed).

What should be provided around the control valve body for maintenance?

Work spaces around the control valve body are to be provided sufficiently for easy removal or reinstall of parts during maintenance.

Can control valves be serviced and repaired?

It’s difficult to make too many blanket statements about servicing and repairing control valves because every situation our technicians walk into is unique. But we’ll try! Here’s are a few of the more common maintenance and repair procedures our technicians perform.
