DINKONDA GLOBAL Power Plants Special Switch Type Straight Through Cut-off Ball Valve, Right Angle Rotary Cut-off Valve, Regulating Valve, Matched With Pneumatic Fork Type Actuator

Product Overview

This pneumatic straight through cut-off ball valve is developed and manufactured by DINKONDA GLOBAL. It is a high-performance switch type automatic control valve, equipped with a pneumatic fork actuator, valve position feedback device, filter pressure reducing valve, solenoid valve, and pressure gauge complete set of accessories. It is mainly used for rapid cut-off and on/off control of industrial pipeline media. It has the characteristics of fast response speed, reliable sealing, and wide adaptability to working conditions. It is widely used in emergency cut-off of process systems and programmable switch pipelines. It is the core cut-off valve in fluid automation systems.

Structural Composition

1. * * Body part * *: Straight through flange ball valve body, standard straight through flow channel, low flow resistance; The valve body material can be selected from WCB carbon steel, 304/316L stainless steel, etc. The valve ball is a solid sphere, and the valve seat adopts a soft seal or metal hard seal structure to meet the sealing requirements of different temperatures and pressures. The flange connection form complies with flange standards such as GB/T, HG, ANSI, etc., making it convenient for pipeline docking.

2. * * Drive actuator * *: Fork type pneumatic actuator, blue housing+aluminum alloy cylinder barrel, high output torque, smooth start stop, can choose between double acting and single acting spring reset types; The fork structure is impact resistant and suitable for high-frequency switching actions.

3. * * Supporting self-control accessories**
-Valve position feedback device (top black limit switch box): real-time feedback of valve fully open/fully closed position signals, can be connected to DCS and PLC control systems;
-Electromagnetic valve: As an air circuit reversing component, it receives electrical control signals to control valve opening and closing;
-Air filter pressure reducing valve+pressure gauge: stabilizes the pressure of the air source, filters and removes water, stabilizes the air supply pressure, protects the actuator, and extends its service life;
-Stainless steel gas source pipelines, connectors, mufflers and other accessories are integrated and shipped from the factory.

Product Features

1 * * Quick cut-off, extremely low flow resistance * *: The straight through spherical flow channel is close to an equal diameter straight through, with low medium flow resistance and quick opening and closing actions, suitable for emergency cut-off conditions;

2 * * Excellent sealing performance * *: The soft sealing type can achieve zero leakage, while the metal hard sealing version is resistant to high temperature and erosion, and suitable for high temperature and particle containing media;

3 * * Integrated set factory * *: The complete assembly and commissioning of the actuator, solenoid valve, pressure reducing valve, and feedback device have been completed. Upon arrival, they are directly connected to the gas source and signal, reducing the workload of on-site assembly and commissioning;

4 * * Visual valve position+remote signal feedback * *: The top feedback device comes with local valve position indication and outputs switch signal, and the central control end monitors the valve status in real time;

5 * * Strong adaptability to working conditions * *: Multiple material combinations can be selected, supporting gas, water, oil, steam, and weakly corrosive chemical media;

6 * * Convenient maintenance * *: Modular accessory design, valve seats, seals, and vulnerable accessories can be replaced separately, and maintenance does not require the complete removal of the valve;

7 * * Explosion proof optional * *: Electromagnetic valves and feedback devices can provide explosion-proof Exd/Exia versions, meeting the requirements for use in explosion-proof areas such as chemical, oil and gas.
