Pn100 High Precision Pneumatic Diaphragm Control Valve with Positioner Single Seated Welding Connection

Product DescriptionSingle Seated Control Valve has a top-guided unbalanced trim structure, It is a compact and simple structure, easy operation and maintenance which can be used under various applications, especially under normal pressure and pressure drop. Valves of this type are the most economical and reliable.Features:  1. Top-oriented action and low-flow resistance design2. Especially suitable for occasions with small pressure differences and can be applied to non-cavitation liquid and gas with noise in the specified range3. Small size, lightweight, simple flow with big capacity in the valve body4. Especially suitable for controlling medium flow with suspended solids and granular. Avoid coking, bonding, and blocking, with good control of high-viscosity liquids and slurries5. By using special materials (carbide, ceramics, etc.) for valve trim and various surface treatment technology (nitriding, hardening treatment), the valve can be used for a variety of harsh conditions6. Plug with precise design makes valve flow to be almost perfect equal percent and linear so that the valve has high precision, high-performance controlling functionBenefits:1. High sealing performance, cost-effective2. Non-pipeline connection can be used for actuator and positioner, with high-speed installation, high reliability, and small installation space. Can be equipped with a multi-spring Pneumatic Diaphragm Actuator or electric mechanism3. Removal and installation of the valve body and trim is simple and this makes future detection and maintenance easier4. The parts commonality is improved and the product cost of manufacturing and maintenance is reduced due to the modular design of the valve trim.Structure:1Body7Disc2Seat Gasket8Stem3Seat9Packing Spring4Bonnet Gasket10Packing5Guide Sleeve11Packing Follower6Bonnet12Packing Flange Product ParametersSpecification: Nominal Diameter (mm)20253240506580100125150200Rated Flow CoefficientLinear6.91117.627.54469110176275440690Equal Percentage6.31016254063100160250400630Rated Travel (mm)16254060Nominal PressurePN16~PN100, CL150~CL600Flow CharacteristicLinear, Equal PercentageRangeability50:1Pneumatic ActuatorDirect-Acting (PDTC)PM280BPM400BPM650BPM1000BReverse-Acting (PDTO)PM280KPM400KPM650KPM1000KDiaphragm Area (cm2)2804006501000Spring Range (KPa)20~100, 40~200, 80~240Air Pressure (MPa)0.14, 0.25, 0.28, 0.4AccessoriesPositioners, I/P Transducers, Volume Boosters, Position Transmitters, Limit Switches, Solenoid Valves, Handwheels, etc. are optional*For important details such as size and weight, please feel free to contact the sales engineer.Performance:Process VariabilityPneumatic Control ValveOrdinary TempLow Temp, High TempIntrinsic Error
