MillerPneumatic sleeveregulating valvesummary:
Pneumatic sleeve regulating valveSmall in size, lightweight, high-performance, and large in capacity, it is in line withIECThe new generation of universal standardsregulating valveProduct. It is suitable for production process systems with general fluid media and process conditions.Pneumatic sleeve regulating valveStructural composition[Regulating valves are usually composed of an electric or pneumatic actuator and a valve body. There are mainly two types of straight stroke: straight through single seat and straight through double seat. The latter has the characteristics of large flow capacity, small imbalance, and stable operation, so it is usually particularly suitable for situations with high flow rate, high pressure drop, and low leakage. The main types of angular travel are:VElectric regulating ball valve, pneumatic diaphragm cut-off valve,Eccentric butterfly valve, etcPneumatic sleeve regulating valveTypes: Classified by purpose and function, main parameters, pressure, medium working temperature, special purpose (i.e. special, dedicated valves), driving energy, structure, etc. The most commonly used classification method is to divide regulating valves into nine major categories according to structure,6The type is straight travel,3The type is angular travel.
This product consists of a new type of pneumatic multi spring thin film actuator and a low flow resistance sleeve valve. The characteristics are as follows:
1Adopting a balanced core, with small unbalanced force, allowing for large pressure difference, and stable operation.
2The large guiding surface of the valve core can improve the oscillation caused by eddy currents and impacts, and reduce damage.
3Reduced noise compared to ordinary single and double seat regulating valves10bdabout.
4The structure is simple and easy to assemble, disassemble, and maintain.
