Explosion proof sanitary ball valves feature stainless steel quarter-turn handles to mechanically lock the valve in open or closed position. They are suitable for diversion, convergence and flow direction switching of flammable and explosive gas, liquid, dust and other media.

Electric explosion proof actuator provides the power to drive the actuation mechanism and to control the operation of the valve. It can accept a 4-20 mA signal to adjust the valve opening and closing.
Flow control

Flow control is an important aspect of many applications. It allows the user to restrict or increase the flow of liquids, gases, or steam. There are different types of valves that can be used for regulating flow. These include ball valves, gate valves, and globe valves.

The VSI Series V is a high performance segmented stainless steel valve for industrial applications with a high level of control and superior close-off. It incorporates a full port, 3-way tri-clamp sanitary ball valve with a 316L stainless steel body and a heavy duty PTFM seat and backup ring that can be replaced in-line with simple hand tools to reduce downtime.

This valve has an explosion-proof electric actuator, which is specially designed for use in flammable and explosive environments. It is made of fireproof materials and uses different cables than ordinary ones to ensure that it doesn’t produce electric sparks in these environments. It also features a range of other features, including manual operation, position indication, and simple connection.

The key to a high-quality sanitary valve is the sealing. This is accomplished with the use of high quality, low-melting, corrosion resistant materials such as PTFE (Polytetrafluoroethylene), and a welded, double block and bleed design.

This ensures that the valve will have a tight shutoff and no leakage even after many cycles of operation. In addition, the valve is designed to be anti-static to protect against electrical sparks that could ignite combustible gasses in the pipeline or equipment.

The electric actuator is enclosed within the explosion proof housing that converts electrical energy to mechanical torque to rotate the valve and control the flow of media. The actuation can be either power to open or power to close and the valve will remain in the last position with loss of power, a very useful feature for safety applications. All components are 316L stainless steel ASTM AF3M and heat stamped for full traceability with CMTR reports provided on each unit.

The explosion proof sanitary ball valve features a simple, three-piece design that easily disassembles to facilitate cleaning and inspection. It consists of a valve body with two flanges, PTFE valve seats, and a ball and stem unit. It can be fitted with either a handle for manual operation or a bonnet and pneumatic actuator for automated operations.

The sanitary PTFE ball valve has excellent corrosion resistance and high sealing performance. It also has a low pressure drop and is water hammer-safe. The PTFE seat and stem are reinforced for longer life, and the valve is easy to maintain with no special tools required.

Explosion proof sanitary ball valves are designed to operate safely in environments with hazardous process fluids or gases. They have a backup metal seat that seals the ball in case of a fire, which reduces leakage and prevents explosions. They also have a fire-safe lip that protects the floating ball from igniting the surrounding process media, and they are antistatic to eliminate static charges that can build up during valve operation.

Performing regular maintenance on ball valves is a crucial step in ensuring the safety of your process system. By identifying issues and fixing them before they cause larger problems, you can save money and avoid downtime.

To maintain the performance of your valves, it is important to lubricate them regularly. This will reduce the friction between the stem and seat, which can increase their life expectancy. It also helps to prevent the formation of rust and corrosion.

Soldering a ball valve can be a simple task for those with some experience and the right tools. To ensure that the job is done correctly, you should always wear protective gear and follow a basic soldering technique. Before beginning the process, make sure that the copper tube ends are cut square and deburred, and the solder cups are clean. You can use a cleaning brush, Scrotch Brite, or emery cloth for this purpose. Then begin the soldering process by concentrating the heat on the tube end and directing it away from the body joint.
