Gate Valve Hydraulic Actuator

The gate is usually wedge shaped.

Gate valve hydraulic actuator.

The linear actuator has proven itself in many applications. Hydraulic fail safe actuator is a advanced equipment supplier which used for both surface and subsea applications in conjunction with magnum gate valves. They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. Hydraulic fail safe actuator houses a quick disconnect mechanism which allows for fast removal of actuator from valve without disturbing the body bonnet connection.

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 valves are so named because the part that either stops or allows flow through the valve acts somewhat like a gate. Applications and compatibility of gate valves and actuators 4 da 1 standard subsea fail safe hydraulic actuator with rotary override for intermediate water depth high performance dhd manual slab gate valve da 3 subsea fail safe hydraulic actuator with linear override da 6 subsea fail safe hydraulic actuator with rotary or linear override for. Linear hydraulic actuators provide more precise control over the piston s movement because liquids are virtually incompressible.

Gate valves with actuators use a threaded stem to connect the actuator to the gate via a drive nut around the. Because liquids are nearly impossible to compress a hydraulic actuator can exert considerable force. Onshore offshore topside variations are available. Valve function throttling valves can be moved to any position including fully open or fully closed within the stroke of the valve.

A hydraulic actuator consists of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. Power operated actuators using gas pressure hydraulic pressure or electricity allow a valve to be adjusted remotely or allow rapid operation of large valves. If the valve has a rising stem its position can be seen just by looking at the position of the stem. When the valve is wide open the gate is fully drawn up into the valve.

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. Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid. 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. The mechanical motion gives an output in terms of linear rotary or oscillatory motion.
