First, detailed materials of the product [pneumatic V type regulates the ball valve ]:
Name of product: The pneumatic Model V piston type regulates the ball valve
Characteristic of the products: ZSHV pneumatic Model V piston type regulates the regular type Model V notch spheroid of having the special form of ball valve and adjustable metal valve seat structure, when the valve is closed , Model V notch and valve flat form Tenneco function of shearing , can prevent from spheroid and valve flat card that filth produce die phenomenon, close the function by oneself , is especially suitable for including the fibre and material thick liquid , the medium of the sewage and viscidity particle, mixing can be realized regulating in succession with the valve positioner, flow and hinder small, it is wide to regulate the range, regulating valve of the high quality that it is one kind to have wide use range. Pneumatic V type regulates the ball valve, regulates the ball valve pneumatically, regulate the ball valve.
Second, the pneumatic Model V piston type regulates the main appearance of the ball valve and connects the size unit (mm ):
