PTFE Seal V Cut Pneumatic Control Valve
PRODUCT DESCRIPTION:
PTFE Seal V Cut Pneumatic Control Valve/Pneumatic/PTFE Seal
Description:
Soft seal V Cut Pneumatic Control Valve is widely used in chemical industry petroleum textile electric power food
and pharmaceutical refrigeration paper and other industries system control.The V- cut in disc can rotate reversely
& correspondingly with metal seal to produce shear force to cut off fibre and prevent the block.
The Innovative & improved metal seal valve has the sealed surface of flange without screw hole to enhance the sealing
strength which can effectively avoid the danger of surface leakage for the metal sealed valve's flange surface.
pneumatic piston actuator is divided into spring-type and spring-free type. When the valve is required to be fully opened
or closed under fault it is equipped with spring type (by restoring tension of spring). When it is required to maintain
position under fault it is equipped with no spring type.It is mainly composed of cylinder body spring piston piston
rod front and rear cylinder head rack output shaft and other components.
Equipped with electrical regulator and air pressure reducing valve the regulation operation can be made by 0.4-0.7mpa air source.
The signal of industrial automation control system can be received by electrical regulator to accurately control
the valve opening so as to achieve the control of flow temperature pressure and other different process parameters.
Features:
* The length of two flanges are shorter than normal ball valve.Without shaft and sleeve makes the connection more easier.
* Specific V-notch cut disc makes the automatic flow volume control mroe stable.
* Optional PTFE and PPL seal material suited for various of pipeline fluids.
* The angular of V-notch cut can be customized according to the CV data of pipeline. It helps to achieve the more precise regulation.
