Jacketed Ball Valve

In many industrial processes, materials such as asphalt, heavy oil, resin, wax, paraffin, and molten chemicals require continuous temperature control to maintain proper flow characteristics. Conventional valves may experience internal blockage when these media cool down and solidify, resulting in increased maintenance frequency and production interruptions.

Xiangzheng Jacketed Ball Valve adopts an integrated full-body jacket structure that surrounds the valve body with a heating channel. Steam, thermal oil, or hot water can circulate through the jacket to transfer heat evenly to the valve chamber, maintaining the required process temperature and ensuring smooth media flow.

The full-jacket design helps minimize cold zones inside the valve and reduces the accumulation of residual materials around the ball and sealing area. This structure is especially suitable for industrial systems where continuous operation and stable temperature control are critical.

Manufactured with WCB carbon steel, CF8 stainless steel, or CF8M 316 stainless steel materials, the valve provides strong mechanical strength and corrosion resistance for different industrial environments. The sealing structure is designed for high-temperature service, supporting reliable shut-off performance under demanding pressure and temperature conditions.

Available in ANSI Class 150, Class 300, and Class 600 pressure ratings, with sizes from 1/2" to 8", Xiangzheng Jacketed Ball Valves can be configured with manual, pneumatic, or electric actuators according to automation requirements.

Installation Precautions

1. Do not operate the jacketed valve beyond its rated pressure and temperature range, to prevent structural deformation and seal damage.

2. Check the inlet and outlet of the jacket before operation to ensure smooth circulation and no leakage.

3. Preheat the valve body before switching when conveying high-viscosity media to avoid ball jamming caused by solidified medium.

4. Do not disassemble the valve or jacket parts under pressure. Completely release pressure and lower temperature before maintenance.

5. Drain residual medium inside the valve and jacket before long-term shutdown to prevent solidification, corrosion and blockage.
