Z961Y High Temperature Motorized Wedge Pressure Seal Gate Valve

The Z961Y series electric motorized gate valve is an industrial-grade, heavy-duty solution engineered for critical isolation services in high-temperature, high-pressure piping systems of thermal power stations and petrochemical plants. Equipped with a high-torque intelligent electric actuator, it allows for smooth, automated remote operations. The advanced pressure seal bonnet utilizes internal fluid line pressure to compress the sealing gasket, ensuring absolute joint tight integrity under extreme thermal cycling and high-pressure differentials.
