ANSI GB Standard Cast Steel Electric Actuated Single Seated Control Valve
Product introduction:
A control valve is a power-operated device used to control or alter the flow of fluids like gas, oil, water, and steam. It moves after receiving a signal from a controller, changing the flow. It is a control device used to manage and direct the flow of fluids by changing the size of the flow route. It offers direct control over flow, temperature, pressure, or liquid level. In order to control the flow of fluid, a control valve uses an actuator to adjust the position of the valve plug or disk. These are applied to keep a process variable as close to the target set point as is practical. The components of this valve installation include a valve body, an actuator, a positioner. The body consists of trim components and a bonnet assembly. Its structure supports seating surfaces and a valve closure part while withstanding fluid static pressure and differential pressure, allowing fluid flow, providing pipe-connecting ends, and all of the above. Pneumatic, hydraulic, or electrically powered actuators are the tools that generate the force needed to open and close the valve. To maintain a desired set-point, positioners track and manage real actuator movement.
ZDLM series electronic type electric regulating valve products with light body and excellent performance, it is a high-quality basic electric control valve product. It is suitable for the production process control system of general fluid process medium process conditions.
This product is composed of 3810L series electronic type electric actuator and fine and sleeve regulating valve. The actuator is an integrated structure with built-in electronic controller module, which can avoid the trouble of additional servo amplifier. It has high precision and easy installation.

Product features:
1. Balanced valve core is adopted, with small unbalanced force, large allowable differential pressure and stable operation.
2. The valve core has a large guiding surface, which can improve the vibration caused by eddy current and impact and reduce damage.
3. The noise is about 10dB (a) lower than that of ordinary single seat regulating valve.
4. Simple structure and convenient disassembly and maintenance.
This series of products have good performance and operation, and can meet the control needs of customers in a wide range of applications.
