ZWZN Electric Double Seat globe Control Valve

ZWZN Electric Double Seat globe Control Valve is  flanged double seated sliding stem control valve . Two seat rings and the plug with stem is a module acessible through the bonnect opening of the body.  The standard design combines the benefits of strong guiding with a semi-balanced design. The balancing of forces extends the pressure and size limit for this series of valve considerably beyond that of a single seated design. The design provides heavy duty top and bottom guides allowing higher flow rates and pressure drops. Because of the semi-balanced trim design, the actutor is usually more reasonable size as well.
