Product Features

• Gear Operation: Equipped with a gearbox, it can easily operate valves with large diameters or under high pressures, reducing the operating torque.

• Double Sealing: Metal-to-metal sealing is adopted between the gate and the seat to ensure zero leakage.

• Rising Stem Design: When the stem rises, the opening and closing state of the valve can be visually displayed.

• Fireproof Design: It complies with the API 607 standard, ensuring that it can still maintain sealing in the event of a fire.

• Anti-static Design: There are anti-static devices between the stem and the valve body to ensure the safety of operation.

• Corrosion-resistant Design: The valve body and main components are made of cast steel or stainless steel, with strong corrosion resistance.

• Compact Design: It has a compact structure and saves installation space.

Application Scenarios

• Petrochemical Industry: Used in oil and gas transportation, reactor feed systems, etc., to ensure the control of high pressure and high flow rate.

• Water Treatment Systems: Used to control the water flow, prevent corrosion and protect pumps and pipeline systems.

• Natural Gas Systems: Used for natural gas transmission to ensure the safe transmission of gas.

• Pharmaceutical and Food Industries: Used to handle corrosive media such as acids and alkalis and ensure aseptic processes.

• HVAC: Used for the flow regulation at the inlets and outlets of hot and cold water systems and heat exchangers.

• Power Plants and Industrial Boilers: Used to control the flow of steam and hot water to ensure the stable operation of the systems.

Installation and Maintenance

• Before Installation: Check whether the inside of the valve is clean and make sure there is no impurity blocking it. Check whether the flange connections are intact.

• During Installation: Ensure that the fluid flow direction is consistent with the arrow mark on the valve body. Tighten the flange bolts evenly.

• Maintenance: Regularly check the sealing performance. If there is leakage, replace the sealing parts in time. Regularly clean the impurities inside the valve body to ensure the normal operation of the valve.
