Knife Gate Valve

Product Description

1. Jacketed gate valve is equipped with an integral metal jacket outside the gate valve body. Steam or thermal oil can be fed into the jacket to trace and insulate the medium inside the valve body. 2. The valve is designed in accordance with ASME B16.34 standard to prevent medium crystallization, solidification and blockage of valve flow passage caused by temperature drop. 3. Materials of body, gate and jacket shell can be selected according to medium and tracing temperature. 4. Applied in pipelines for easy-solidifying media such as heavy oil, resin and paraffin wax to maintain medium fluidity and avoid solidification and blockage inside valve body.

Features & Benefits

1. Full enveloped integral jacket, most of the body surface is traced for uniform and stable heat tracing performance. 2. Jacket connections can accept multiple heating media, compatible with steam, hot water and thermal oil tracing processes. 3. Jacket shell features high pressure resistance and reliable welding process with no leakage risk. 4. The gate valve body retains original shut-off function for full open and full close isolation of medium. 5. Stress relief treatment is applied on welding joints between jacket and body for fatigue resistance under thermal cycling conditions. 6. The jacket is equipped with vent and drain ports to facilitate discharge of condensate inside the jacket.
