description
LT lug type pneumatic butterfly valve product overview and use
The LT lug type pneumatic butterfly valve is composed of a pneumatic actuator and a centerline butterfly valve. The pneumatic butterfly valve is equipped with a stroke limit switch, a solenoid valve, a triple piece and a 0.4-0.7MPa air source to achieve switch operation, and sends out two pairs of passive contact signal instructions The opening and closing of the valve. Matching with electric
positioner, input 4-20mADC signal and 0.4-0.7MPa air source to realize intelligent control, realize the adjustment of pressure, flow, temperature, liquid level and other para
meters. It is powered by compressed air, and the valve stem drives the valve core to rotate 90°C in the valve body, which can achieve a fully open-fully closed action. The product is divided into metal seal and soft seal according to its sealing performance. It can be widely used in industrial automatic control systems such as petroleum, chemical, offshore, and drilling platforms for remote centralized control or local control.
Features and standards
The high platform design conforms to the ISO5211 standard, and can be directly connected to the ISO5211 standard actuator. Good interchangeability
