The pneumatic emergency shut-off orbit ball valve is a 90-degree rotary valve adopting a stem-lifting linkage structure. During valve opening and closing, the ball lifts off the seat first and is completely suspended inside the valve cavity before performing a 90-degree rotation. Throughout the whole operation process, the ball sealing surface has no contact or friction with the valve seat, achieving zero wear and effectively solving the common problems of sealing wear and failure existing in traditional ball valves. Equipped with a forced sealing function, the valve realizes reliable compression sealing under emergency working conditions. Its unique zero-friction structural design ensures long-term stable and reliable sealing performance, fully complying with the ANSI B16.104 VI sealing standard.
This series of valves features an ultra-fast emergency shut-off response speed. All models can cut off approximately 95% of the fluid flow within 0.5 seconds. Valves with DN40–DN200 nominal diameter can achieve full closure in 1–3 seconds, while large-diameter valves of DN250–DN600 can be fully closed within 3–5 seconds. It can quickly cut off pipeline media in case of sudden emergencies, effectively avoiding potential safety hazards.
The valve is equipped with an automatic reset and shut-off function for power and air loss. It will automatically close urgently once the system suffers power or air failure, keeping the pipeline system under controllable and safe conditions at all times and providing solid safety guarantee for industrial production pipelines.
Different from conventional valves with traditional manual operating mechanisms, this product adopts an intelligent automatic control system combined with a standby air source auxiliary control design for higher safety redundancy. Fitted with a dedicated standby air storage tank, the valve can be preset to FC (Fail Closed) or FO (Fail Open) state according to on-site working conditions before delivery. In the event of power or air failure, the valve automatically executes the preset opening or closing action and locks in a safe state. It will automatically return to normal operation after faults are eliminated, perfectly meeting the safety interlock requirements of various high-risk working conditions.
In addition, the valve is equipped with a professional L-type three-way reversing valve, which replaces the traditional manual operating mechanism of pneumatic valves. Under power and air failure conditions, rotating the handle counterclockwise by 90 degrees can activate the standby air storage tank to complete one full valve opening and closing operation, realizing emergency manual control and adapting to various fault working scenarios.
Pneumatic Shut‑off Ball Valve are 0‑90° rotary valves. They utilize pneumatic actuators to convert compressed air into rotary motion, delivering fast and reliable valve opening and closing for industrial process control.
According to specific application requirements, pneumatic ball valves can be equipped with solenoid valves, limit switches, position feedback devices, air filter‑regulators, valve positioners and other pneumatic instrument accessories to realize automatic valve control and remote monitoring functions.
Many factors shall be considered when selecting a pneumatic ball valve, including valve size, pressure rating, operating temperature, process medium, flow rate, body material, seat material, actuator type and control mode.

Adopting a zero‑friction forced‑sealing structure, it maintains reliable sealing performance even after over 100,000 frequent on‑off cycles. It cuts off 95% of the flow within 0.2 seconds, with full closure achievable in 3‑20 seconds for manual operation, 1‑5 seconds for pneumatic actuation and 5‑15 seconds for electric actuation. Its torque is only 1/4 of that of conventional products for easy operation. Soft‑sealed versions allow on‑line secondary forced compensation for sealing, feature self‑cleaning sealing surfaces and deliver bidirectional double‑sided sealing.
