Control Valves

A control valve is a power operated device which modifies the fluid flow or pressure in a process control system. It consists of a valve connected to an actuator mechanism that is capable of changing the position of a flow controlling element in the valve in response to a signal from the controlling system. The design of the seat and the plug determines the flow coefficient (KV) and the flow characteristic, as well as the seat leakage rate of a control valve.

The IndiTech Series 210 control valves offers a variety of valve sizes, materials and trim options to cover a wide range of control applications within the power, process and other industries. The valve bodies are specially designed using latest CFD techniques, to ensure a smooth flow pattern and reduced turbulence.

The valve internals are optimized based on the specific application, with special designs available for severe service applications requiring anti-cavitation or low-noise trims. In order to increase the service life, metallic seats and plugs can also be provided with a Stellite hard facing. A variety of shut-off classes from Class IV to Class VI are available to meet the process requirements. The complete range of Series 210 control valves offers excellent controllability, and easy maintenance. Customized valve constructions to meet customer specifications can be engineered. Further versions are available with heating jacket for applications where the process media may solidify below a certain temperature. For applications where high noise levels are anticipated, additional silencers can be provided along with the control valves.

The Series 210 control valves have interchangeable parts, thereby reducing inventory costs. Thanks to their modular design, the control valves can be equipped with various accessories like positioners, limit switches, solenoid valves etc. Pneumatic actuators of different sizes can be coupled depending on the actuating force required. Optionally, electric or electro hydraulic actuators are also available.
