◆ Product Overview: 

 The regulating valve generally refers to the control valve. The control valve is composed of two main components: the valve body assembly and the actuator assembly (or actuator system), which is divided into four series: single-seat series control valve, double-seat series control valve, sleeve series control valve and self-powered series control valve. Variations of four types of valves can lead to many different applicable structures, each of which has its own special applications, characteristics, advantages and disadvantages. 

◆ Nominal diameter: DN20-DN200 

 ◆ Valve body material: stainless steel, cast steel, cast iron, forged steel 

 ◆ Control mode: switch type, adjustable type, pneumatic control, electric control 

◆ Features: 

 1. There are various types of control valves, and they are suitable for different occasions. Therefore, the type of control valve should be reasonably selected according to the requirements of the process production process. 

 2. There are two types of pneumatic control valves: air opening and air closing. The gas-open control valve is closed when it is in a faulty state, and the air-off control valve is opened when it is in a faulty state. Some auxiliary devices can be used to form a position-preserving valve or make the control valve self-locking, that is, the control valve maintains the valve opening before the failure in case of failure. 

 3. The way of gas opening and air closing can be realized through the combination of positive and reactive actuator types and positive and reverse valves. When using a valve positioner, it can also be realized through the valve positioner. 

 4. Each control valve has different structures and its own characteristics.

Each process, each facility, and each environmental constraint has its own special requirements. As a result, Kinko offers a comprehensive range of products that include different performance levels, pressures, functions and materials.
