Single 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 design
2. Especially suitable for occasions with small pressure differences and can be applied to non-cavitation liquid and gas with noise in the specified range
3. Small size, lightweight, simple flow with big capacity in the valve body
4. Especially suitable for controlling medium flow with suspended solids and granular. Avoid coking, bonding, and blocking, with good control of high-viscosity liquids and slurries
5. 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 conditions
6. 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 function
Benefits:
1. High sealing performance, cost-effective
2. 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 mechanism
3. Removal and installation of the valve body and trim is simple and this makes future detection and maintenance easier
4. The parts commonality is improved and the product cost of manufacturing and maintenance is reduced due to the modular design of the valve trim.
