Electric Actuated Flanged Floating/Trunnion Control Valve
Electric Actuated Control Valve Introduction:
Straight stroke electric regulating diaphragm valve (electric regulating valve) has the advantages of simple structure, small flow path resistance, larger flow force than other valves of the same caliber, no leakage, and can be used for the regulation of high viscosity and suspended particle fluids. (rubber or polytetrafluoroethylene) suitable for regulating strong alkali, and strong corrosive medium. It is composed of a diaphragm valve and series electric actuator. There is a servo system in the electric actuator, no need for an additional servo amplifier, and the operation can be controlled with an input control signal (4-20MA or 1-5VDC) and a single-phase power supply to realize the adjustment of parameters such as pressure, flow, temperature, and liquid level.
Working Principle Of Modulating Valve:
1. In the closed position, the ball is pressed against the valve seat by the mechanical pressure of the valve stem.
2. When the hand wheel is turned counterclockwise, the valve stem moves in the opposite direction, and the angular plane at the bottom makes the ball disengage from the valve seat.
3. The valve stem continues to lift and interacts with the guide pin in the helical groove of the valve stem, causing the ball to start rotating without friction.
4. Until it reaches the fully open position, the valve stem is raised to the limit position, and the ball rotates to the fully open position.
Applications Of Throttle Valve:
1. Air-conditioning fan coin(HVAC)
2. water treatment
3. Chemical process
4. Small equipment for automatic control
5. Replacing solenoid valve, particularly when solenoid cannot work reliably
