Gate Valve Hydraulic Actuator

Gate valves hydraulic pacson s hydraulic gate valve is available in sizes from 1 2 to 12 in all materials and pressures up to 15 000psi.

Gate valve hydraulic actuator.

Power operated actuators using gas pressure hydraulic pressure or electricity allow a valve to be adjusted remotely or allow rapid operation of large valves. Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like a gate. The linear actuator has proven itself in many applications. Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid.

If the valve has a rising stem its position can be seen just by looking at the position of the stem. Its simple yet robust design compact profile for tight piping runs reliability of operation and adaptability to hydraulic or pneumatic power sources make it a very viable choice for use with gate or other rising stem valves. Onshore offshore topside variations are available. When the valve is wide open the gate is fully drawn up into the valve.

Hydraulic fail safe actuator is a advanced equipment supplier which used for both surface and subsea applications in conjunction with magnum gate valves. Gate valves are used when a straight line flow of fluid and minimum flow restriction are needed.

The mechanical motion gives an output in terms of linear rotary or oscillatory motion.

They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. Hydraulic fluid is pumped into the cylinder to push the piston forward and removed to pull it back. Linear hydraulic valve actuators linear actuators move linear valves such as gate globe diaphragm and pinch valves by sliding a stem that controls the closure element. Gate valves with actuators use a threaded stem to connect the actuator to the gate via a drive nut around the.

The gate is usually wedge shaped. A valve actuator is the mechanism for opening and closing a valve manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. A hydraulic actuator consists of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. Because liquids are nearly impossible to compress a hydraulic actuator can exert considerable force.
