Gate Valve Hydraulic Actuator

If the valve has a rising stem its position can be seen just by looking at the position of the stem.

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. They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. Gate valves with actuators use a threaded stem to connect the actuator to the gate via a drive nut around the. Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid.

Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like a gate. 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. When the valve is wide open the gate is fully drawn up into the valve. 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 used when a straight line flow of fluid and minimum flow restriction are needed. 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. Hydraulic fail safe actuator is a advanced equipment supplier which used for both surface and subsea applications in conjunction with magnum gate valves. A hydraulic actuator consists of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation.

Hydraulic fail safe actuator houses a quick disconnect mechanism which allows for fast removal of actuator from valve without disturbing the body bonnet connection. Onshore offshore topside variations are available. Linear hydraulic actuators provide more precise control over the piston s movement because liquids are virtually incompressible. 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.

The mechanical motion gives an output in terms of linear rotary or oscillatory motion. Hydraulic fluid is pumped into the cylinder to push the piston forward and removed to pull it back. Valve function throttling valves can be moved to any position including fully open or fully closed within the stroke of the valve.
