Metal Seal V Notch Pneumatic Ball Valve Stainless Steel High Pressure

Metal Seal V-Notch Pneumatic Control Valve


PRODUCT DESCRIPTION:


Metal Seal V-Notch Pneumatic Control Valve/Pneumatic/Metal Seal


Description:

The V-notch cut in disc can rotate reversely & correspondingly with metal seal to produce shear force to cut off fibre and prevent the block. This valve is special suitable for mud and fibrous media and suspended solids containing minimal media.


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.


Metal Seal V-Notch Pneumatic Control Valve

(1) The scissors shape section of valve seat and the disc easily cut off all kinds of impurities in the pipeline effectively ensure smooth flowing of the pipeline .
(2) Stellite seal ring,for high temperature resistance up to 350ºC
(3) Fixed ball valve stem ball core integration effectively solve the problem of mechanical return error rotary error ≤0.5%.
(4) Unique long stem body structure effectively increase the distance between the actuator and high temperature media better heat dissipation performance.
