Characteristics
The installation position, height, and inlet/outlet direction of gate valves should meet the design requirements, and the connection should be firm and tight; Handwheels, handles, and transmission mechanisms are not allowed to be used for lifting and collisions are strictly prohibited; Before opening a gate valve with a bypass valve, the bypass valve should be opened to balance the pressure difference between the inlet and outlet and reduce the opening force.

Advantages
1. Low fluid resistance:
The gate valves for water, valve body is a straight through type. When the valve is fully opened, the gate completely moves out of the flow channel, and the direction of the medium flow does not change, resulting in low flow resistance.
2. Good sealing performance:
The sealing surface of SS gate valves is usually precision machined and has multiple sealing forms to choose from, such as hard sealing and soft sealing, which can achieve good sealing effect and prevent medium leakage.
3. Effortless operation:
Compared to globe valves, CF8 gate valves are easier to open and close.

Packing
Standard export wooden case packaging

Application Scenarios
The stainless steel gate sluice valves widely used in chemical industrial park, pharmaceutical pure water, seawater desalination system pipeline.
