First, Fixed Electric Ball Valve Overview

Q947 Fixed Electric Ball Valve for two cut, adjust the occasion. The connection of the valve to the actuator adopts the direct connection mode, the built-in servo system of the electric actuator, without the need of reprovision servo amplifier, input 4-20mA signal and 220VAC power supply can control the operation. It has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable operation. Actuator can be configured according to user requirements UNIC, PSQ, HQ, DHL and other models of electronic electric actuator or GTX, AL and other piston actuator.

Fourth, The Fixed Electric Ball Valve Product Features

The Q947 fixed ball valve is a new generation of high performance ball valve for long-distance pipeline and general industrial pipeline, its strength, safety, resistance to harsh environment in the design of a special consideration for a variety of corrosive and non-corrosive Sexual medium. It is compared with the floating ball valve, the work, the valve before the fluid pressure on the sphere of the force generated by all the bearings, will not move the ball to the valve seat, so the valve seat will not withstand excessive pressure, so the fixed ball valve The torque is small, the valve seat deformation is small, sealing performance is stable, long service life, suitable for high pressure, large caliber occasions. Advanced spring pre-seat components, with self-tightening characteristics, to achieve upstream seal. Each valve has two seats, each direction can be sealed, so there is no flow to the installation restrictions, is two-way. 
 
The valve has two and three block two body structure, the flange with bolts, sealed with enhanced PTFE embedded in the stainless steel ring, the back of the steel ring without spring to ensure that the seat close to the ball, keep seal. Up and down the stem are not PTFE bearings, reduce friction, operation effort, small shaft at the bottom of the adjustment film, to ensure that the ball and the seal of the junction position.
