Brief Introduction

Z941H electric gate valve is mainly used for high and medium pressure flange connection gate valves. It is suitable for pipelines of various systems in petroleum, chemical, hydropower, and thermal power plants with nominal pressure PN1.6~16.0MPa and working temperature -29ºC~550ºC to cut off or connect pipeline media. Applicable media are: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. The gate valve can be installed on horizontal pipelines or vertical pipelines. Single and double gate valves should be installed on horizontal pipelines, and the handwheel should be located above the valve. It is not allowed to be installed downward. The flow direction of the gate valve medium is not restricted. Flange connection is usually used, and welding connection is also used in special occasions. For large-diameter and high-pressure gate valves, the opening and closing torque is large. In order to reduce the opening and closing torque, the bypass valve can be installed. The bypass valve is installed outside the main gate valve. Its inlet and outlet are connected to both sides of the main gate valve and are interconnected. The bypass valve should be opened before the main gate valve is opened. After entering the valve, the pressure difference before and after the gate of the main gate valve is reduced, thereby reducing the opening torque of the main gate valve. The selection of the bypass valve diameter should be based on the main valve diameter and usage requirements.
