Product Overview
This Pneumatic Top Entry Ball Valve adopts an integrated thickened top-entry body, equipped with a special quarter-turn pneumatic actuator, combining two core advantages of inline maintenance without pipeline disassembly and pneumatic automatic control.
Manufactured in strict accordance with international common valve standards such as API 6D, API 598 and ASME B16.34, it features quick switching and stable sealing, and can be connected to PLC, DCS and other industrial automatic control systems for remote pneumatic on-off control. It is suitable for key industrial pipelines requiring automatic control and inconvenient shutdown maintenance, such as petrochemical, oil and gas gathering, municipal pipe network, power plants and metallurgy.
Key Features
1. Top-entry Structure for Easy Maintenance
Adopt integral forged or precision cast one-piece body to eliminate leakage hidden dangers of split body. All internal parts are assembled and disassembled from the top for maintenance. During on-site overhaul, there is no need to remove the flanges and pipelines at both ends of the valve. Just loosen the top bonnet bolts, and the core wearing parts such as ball, seat and stem can be quickly taken out, which greatly shortens the downtime and reduces the operation and maintenance workload. It is especially suitable for complex working conditions where pipeline disassembly and displacement are inconvenient, such as high-altitude laying, underground pipe networks and large calibers.
2. Efficient Pneumatic Actuation, Stable Automatic Control
Standard industrial grade quarter-turn pneumatic actuator, available in double acting and single acting spring return types, which can automatically reset in fault state to ensure pipeline safety. Driven by clean compressed air, the actuator features fast switching and stable output torque, with precise mechanical limit to avoid jamming and overtravel, and runs silently. It can be equipped with solenoid valve, limit switch, air filter regulator and other accessories to easily realize remote pneumatic control, suitable for various industrial automation scenarios.
3. Tight Sealing, Bidirectional Zero Leakage
Floating ball self-energized sealing structure, the medium pressure pushes the ball to fit the seat, the higher the pressure, the tighter the seal, realizing two-way sealing without leakage. The soft seal type is equipped with high-precision PTFE/PPL seats, which are precisely ground and paired, reaching ANSI B16.104 Class VI zero leakage. The hard seal type can be optional with Stellite alloy overlay, which is high temperature resistant, erosion resistant and wear resistant, suitable for harsh working conditions such as high temperature steam and media with a small amount of particles.
4. Rigid Body, Stable Operation
One-piece body resists pressure and deformation, suitable for high-pressure and alternating temperature services. Full bore polished channel ensures low flow resistance and smooth medium flow without accumulation.
5. Full Protection, Wide Application
The pneumatic actuator is standard with IP67 protection, waterproof and dustproof, adaptable to harsh environments such as outdoor and humid conditions. Explosion-proof type ExdⅡBT4/CT4 is optional for flammable and explosive media such as natural gas and oil. The valve body is equipped with API 607 fire-safe structure, anti-static device and bottom-mounted blow-out proof stem, comprehensively eliminating potential safety hazards such as static fire, stem ejection and medium leakage, meeting the safe operation requirements of high-risk working conditions.
Applications
Petrochemical, oil & gas gathering, municipal heating and water supply, power plants, sewage treatment, metallurgy, coal chemical and other industrial pipelines requiring pneumatic automatic control and convenient inline maintenance.
Product Summary
This valve focuses on the two core highlights of pneumatic automatic control and convenient top-entry maintenance. It has a rigid body, excellent sealing performance, fast and stable switching, and is fully compliant with international API standards. It is an optimal choice for industrial pipelines with high pressure, large caliber and remote pneumatic control needs.
