Product Details
DINKONDA GLOBAL Power Plants Special RQ Series Single Acting Pneumatic Switch Ball Valve, High Torque Single Acting Pneumatic Actuator And WCB Cast Steel Flange Ball Valve
Product Overview
The RQ series single acting pneumatic switch ball valve complete set device consists of an RQ high torque single acting pneumatic actuator and a WCB cast steel flange ball valve body, belonging to an angular stroke two position shut-off valve. Using compressed air as the power source and a single acting spring reset structure, the valve can be safely reset (fault closed/fault open) automatically by relying on the built-in spring under gas and power outage conditions. Complete set of solenoid valves, air filter pressure reducing valves, valve position feedback limit switches, air source pipeline accessories, receive control system switch signals, and complete rapid on/off control of pipeline media. The product has high output torque, fast opening and closing speed, and reliable sealing performance. It is suitable for process pipelines such as petroleum, chemical, thermal and electric, heating, coal chemical, water treatment, etc., especially for working conditions with safety interlock and emergency cut-off requirements.
Structural Composition
1. RQ single acting pneumatic actuator
High torque fork type pneumatic actuator, dual cylinder structure, output 90 ° angular stroke; Equipped with a large capacity reset spring component, it belongs to a single acting type. When the gas is supplied, the valve is driven to move, and when the gas is lost, the spring is forced to reset, achieving fault safety protection. The shell is made of high-strength carbon steel material and coated with a red anti-corrosion coating as a whole; Internal fork transmission structure, high output torque, smooth opening and closing, suitable for large-diameter and high-pressure differential ball valve working conditions. The top integrated installation interface can directly assemble accessories such as solenoid valves, filter pressure reducing valves, valve position feedback devices, pressure gauges, etc. The air circuit is arranged in an integrated manner, and the structure is compact.
2. Cast steel ball valve body
Valve body material WCB carbon steel, flange connection, floating ball structure; Metal+soft seal combination, tight switch cut-off, low leakage level; The valve stem adopts an anti flying structure, and the packing combination is sealed, which is resistant to high temperature and medium erosion; The valve body comes with a supporting base to reduce the impact of pipeline stress on the valve. It has a nominal diameter of DN50-DN300 and a nominal pressure of PN16-PN63, and is suitable for various media such as liquids, gases, and steam.
3. Complete set of accessories
Electromagnetic valve: Two position five way, receiving DC24V/AC220V switch signals, switching the pneumatic control actuator for opening and closing, optional explosion-proof type;
Air filtration pressure reducing valve: filters and regulates the air source to provide a stable and clean driving air source;
Valve position limit feedback switch: mechanical/proximity switch, remote feedback valve fully open and fully closed position signal;
Pressure gauge: visually monitor the working pressure of the gas source on site;
Gas source pipeline joint: stainless steel fittings, corrosion-resistant, and securely connected.
Product Features
1. Single acting spring reset, safety interlock
Built in strong spring components, automatically reset in case of gas supply interruption or power loss, meeting the safety requirements for emergency shutdown of processes, and can be set to fault off or fault on as needed.
2. High torque fork drive, suitable for large-diameter high-pressure differential
Compared to gear and rack, fork type transmission has a larger output torque and can drive large-diameter ball valves of DN200 and above, overcoming the opening and closing resistance caused by medium pressure difference.
3. Reliable sealing and excellent cutting performance
The floating ball sealing structure of the ball valve achieves tight cutting after closing; The valve stem is sealed with multiple packing materials to reduce external leakage, making it suitable for pipelines with flammable, explosive, and toxic media.
4. Integrated accessory configuration
The complete set of valve position feedback, electromagnetic reversing, and air source processing accessories are assembled and shipped from the factory. Only the air source and control signals need to be connected on site to be put into use, reducing the workload of on-site installation and debugging.
5. Good anti-corrosion and protective performance
The actuator shell is treated with anti-corrosion coating, and the pipe fittings are made of stainless steel material; Electrical accessories support explosion-proof selection and can be used in chemical explosion-proof areas.
6. Low flow resistance, quick opening and closing
The ball valve has a full bore flow channel with minimal medium pressure loss; Pneumatic drive has a short opening and closing time, which can quickly achieve pipeline connection and disconnection.
