Explosion-Proof Electric Ultra-Short Ball Valve
The Explosion-Proof Electric Short Pattern Flanged Ball Valve is a high-safety automated valve designed for flammable and explosive environments, featuring a stainless steel or WCB body with PTFE/PPL seals for zero leakage and corrosion resistance, integrated with explosion-certified electric actuators to enable rapid 90° switching or precise flow control. Ideal for oil & gas, chemical,…
Features
- It features a compact structure, small size, light weight and convenient installation.
- It is mainly used to shut off or connect the medium in pipelines, and can also be applied to the regulation and control of fluids.
- The valve seat adopts sealing rings made of elastic materials such as PTFE. Due to the excellent self-lubricating property of PTFE and similar materials, the friction loss with the ball is low, effectively extending the service life of the product.
- The valve stem seal is reliable. Since the stem only rotates without lifting movement, the packing seal of the stem is not easily damaged, and the sealing performance increases with the rise of medium pressure.
- The bottom‑mounted valve stem is designed with a protruding shoulder to prevent stem blowout. In the event of fire damage to the stem seal, metal‑to‑metal contact can be formed between the shoulder and the stem to ensure sealing.
- It is widely used in petroleum, chemical, metallurgical, power station, light industry and other fields for automatic regulation or on‑off control of oil, water, gas, pulp and fibrous fluids.
- Anti-static function: Springs are installed between the ball, stem and valve body to discharge static electricity generated during the opening and closing operation.
