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. The stem may be classified as rising or non rising depending on which end is threaded. In addition to popular end connection options these valves can be ordered with mueller s exclusive aquagrip system that incorporates an o ring sealed compression connection and integral pipe. Hydraulic actuators product line model hx omni cast gate valve model cs r omni forged gate valve model fs r other manufacturers model hwx model hdx omni offers hydraulically actuated valve assemblies ready to deploy directly into service or as actuated bonnet assemblies ready to mount on valves from other manufacturers. Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like a gate.

The actuator is designed to maintain the valve reverse acting in the open position with hydraulic pressure on top of the piston. Loss of hydraulic pressure allows pressure in the valve body to move the stem and gate into the closed position. The gate valve is now fully open. When the valve is wide open the gate is fully drawn up into the valve.

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. Shafer sh series double acting hydraulic gas over oil actuator is perfect for small valve pipeline applications for safe performance. Mueller resilient wedge gate valves have features to make them easier to operate preserve sealing capability and interior coating integrity for many years of reliable service. Gate valves are used when a straight line flow of fluid and minimum flow restriction are needed.

The linear actuator has proven itself in many applications. Gate valves with actuators use a threaded stem to connect the actuator to the gate via a drive nut around the threads allowing the nut to be turned with a hand wheel or motor. They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. The extended stem indicates the valve is closed.
