Gate Valve Actuator

A manual gate valve left and a gate valve with linear actuator.

Gate valve actuator.

They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. 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. Turnkey valve operating system actuator control package an integrated turnkey option for the toughest flow control automation challenges from one supplier. This power source can be electric pneumatic compressed air or hydraulic the flow of oil.

Operating torque is the most important parameter to select the gate valve electric device the output torque of the electric actuator should be 1 2 1 5 times the maximum torque of the gate valve operation. 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. Linear actuators provide thrust rather than torque which is a direct function of the cylinder s size since the actuator s thrust is the product of the pressure the hydraulic fluid or air exerts and the cylinder s surface. A valve actuator is a mechanical device that uses a power source to operate a valve.

It is intended for duty as a stop valve and in the fully open position provides straight through full bore flow with consequent minimum loss of pressure of the service fluid. A gate valve with linear actuator. There are two main types of actuators one for each of the two main types of valves that require them. They are rotary and linear.

Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid. The linear actuator has proven itself in many applications. Actuator technology for best in class valve control and automation ensuring constant operational safety and reliably. Sharpe is part of smith cooper international.

Power operated actuators using gas pressure hydraulic pressure or electricity allow a valve to be adjusted remotely or allow rapid operation of large valves. Econ offers a variety of valve and valve related products including our ball valves butterfly valves double block and bleed expanding plug valves control valves solenoid valves pneumatic and electric valve actuators valve position limit switches and analog and digital valve positioners. In this valve a gate like disk is moved at right angles across the line of flow between matching seats in the valve body thus opening or shutting off the flow.
