What is the NST-NORDSTEAM Linear Control Valve that is causing a stir in the Vietnamese valve market? Is this NST valve really good, and how much does it cost? Join Tan Thanh Company to explore this control valve.
PNEUMATIC CONTROL VALVE NST-NORDSTEAM PROPORTIONAL
This is a combination of the NST-OKV1 control valve and the 4~20mA linear positioner NST-PL02, serving as a compressed air control valve. It provides the capability to control and measure various substances such as refrigerants, cooling water, hot water, heat transfer oil, steam, combustible gases, and other liquids as needed.
The NST-OKV1 control valve is widely used in industrial complexes, architectural projects, and the mechanical manufacturing industry.

Linear Control Valve Operating Principle
The operating principle of the linear control valve differs from that of butterfly or ball valves, as they open and close based on linear motion rather than rotational movement. The valve’s stroke depends on its size.
When the control head is powered, the motor generates torque through the gear transmission system to the valve shaft, enabling the valve to operate. The 4 ~ 20mA signal is divided to allow the motor to operate with different opening angles for a percentage of the fluid flow through the adjustable valve.
When the preset state is reached, the circuit board automatically cuts off the power, locking the position to allow the valve to operate steadily at the current moment. The presence of buttons on the display facilitates easy, modern, and convenient adjustment of the valve.
