DINKONDA GLOBAL Power Plants Special RQ Series Pneumatic Switch Type Flange Butterfly Valve, Angular Stroke Pneumatic Actuator And Flange Type Soft Seal Butterfly Valve

Product Overview
The RQ series pneumatic switch type butterfly valve complete equipment consists of an angular stroke pneumatic actuator and a flange type soft seal butterfly valve body. It uses compressed air as the power source to achieve a two position switch action of fully open and fully closed valves. Complete set of accessories such as solenoid valves, air filter pressure reducing valves, and feedback limit switches can receive electrical signals from the central control system switch, remotely feedback the valve on/off position status, and achieve automatic control of pipeline medium on/off. The product has a compact structure, fast opening and closing, low flow resistance, and good sealing performance. It is suitable for working conditions such as water, air, sewage, and circulating media, and is widely used in industrial pipelines such as thermal power, heating, water treatment, HVAC, and chemical engineering. It is used as a pipeline cutting and on/off protection equipment and can meet various process requirements such as on-site explosion prevention and fault safety reset.

Structural Composition
1. RQ angular stroke pneumatic actuator
Adopting a gear rack angular stroke structure, it outputs a 90 ° angular stroke and drives the butterfly valve to achieve opening and closing actions; It is divided into two types: double acting and single acting (spring reset). The single acting model relies on the spring force to automatically reset in the event of gas or power loss, achieving fault on or off safety protection. The shell is made of aluminum alloy material, treated with hard anodizing and anti-corrosion treatment. The internal rack and pinion transmission pair has a smooth transmission, high output torque, and low friction loss; The output shaft connection interface complies with ISO standards and is easy to disassemble and exchange.

2. Flange butterfly valve body
The valve body is made of ductile iron material and connected by flanges; The valve plate is made of ductile iron with nickel plating protection, and the valve seat is sealed with rubber soft seal, which is reliable and has low leakage in the closed state; The overall flow channel is unobstructed with minimal pressure loss; The flange size follows the national standard GB/T, which is easy to disassemble and maintain, and is suitable for neutral medium pipelines at room temperature.

3. Complete set of supporting accessories
Electromagnetic valve: receives electrical switch signals, switches the gas path, controls the actuator to change direction, and realizes valve opening and closing. It can be selected from ordinary and explosion-proof types.
Air filtration pressure reducing valve: filters, removes water, regulates pressure of compressed air from the air source, outputs stable and clean air source, and protects internal components of the actuator.
Valve position feedback limit switch: mechanical/proximity type feedback device, which converts the fully open and fully closed positions of the valve into switch signals and feeds them back to the control room for remote status monitoring.
Gas source pressure gauge: visually check the gas supply pressure on site for easy debugging and inspection.

Product Features
1. Fast opening and closing speed, reliable action
Gear rack angular travel actuator, with rapid opening and closing of 90 ° rotation; The single acting spring reset model automatically returns to a safe position in the event of gas and power outages, ensuring the safety of the process system.

2. Excellent sealing performance
Rubber soft sealing structure, achieving zero leakage after closure, suitable as a pipeline shut-off valve; Valve body flange connection, uniform installation force, good pressure stability.

3. Attachment integration, high degree of automation
A complete set of integrated solenoid valves, filter pressure reducing valves, and valve position feedback switches can be put into use by connecting the gas source and control signals; Remote control and location feedback are available, without the need for on-site manual operation. Electrical accessories can be provided in explosion-proof versions to meet the needs of hazardous areas such as chemical engineering.

4. Convenient maintenance
Standardization of the connection interface between the actuator and the valve body, with strong universality of components; The replacement of butterfly valve seats and seals is simple, and the cost of later maintenance is low; The aluminum alloy actuator housing is lightweight, corrosion-resistant, and suitable for indoor and outdoor industrial environments.

5. Wide adaptability to working conditions
Can be used for circulating water, cooling water, sewage, air and other media; Supports forward and reverse pressure, suitable for heating and heat exchange systems, power plant auxiliary water systems, and water supply and drainage pipelines.
