The main feature of the two-way sealed knife gate valve series is that it can provide sealing in both directions, which is suitable for occasions where the fluid flow direction is not fixed. The design of this type of valve includes a double sealing structure, which can prevent fluid leakage and withstand high pressure and temperature. Common types include:
Soft seal two-way knife gate valve: uses elastic materials (such as rubber or plastic) as the sealing surface, suitable for low to medium pressure applications.
Hard seal two-way knife gate valve: uses metal sealing surface, suitable for high pressure and high temperature environments, such as petroleum, chemical and other industries.
Fully welded two-way knife gate valve: The valve body and pipeline are welded, which enhances the sealing performance and high pressure resistance, and is often used in high-demand working conditions.
Manual/electric two-way knife gate valve: manual or automatic control mode can be selected as needed, suitable for different operating frequencies and environments.
The design of this valve ensures good sealing even when the fluid flow direction changes, suitable for complex or changing fluid flow scenarios.
The valve body of LGD series knife gate valve is of double-piece closed design, which attains the machining of the inner cavity of the valve body, and the valve body can be fully lined with rubber or polyurethane. This product has passed ISO5208-2.0Mpa test and obtained 0 leakage rating.
It adopts the patented 45-degree fit of the gate edge and sealing surface, which strengthens the sealing of the valve without increasing the opening torque, and realizes a good performance of 0 leakage in the middle cavity after 5,000 times gate opening and closing test .
