Cast Iron Butterfly Balance Valve 1.0 /1.6 Mpa Flanged Butterfly Valve

Usage

This valve can be used for shutting off, switching on and regulating the flow of pipes and equipment in non-corrosive mediahe balance valve is a valve with special functions. It is an ideal new energy-saving product. It has good flow characteristics, can distribute flow reasonably, solve the hydraulic imbalance problem in the pipe network, and it can accurately adjust the pressure drop and The flow rate improves the flow state of themedium in the pipe network to achieve the purpose of medium balance.

Structure and action principle

1. By operating the worm gear device, the valve shaft rotates 90 °, driving the butterfly plate to rotate 90 °, so as to open or close the product. The flow can be adjusted arbitrarily according to the characteristics of the worm gear device. The small pressure measuring valve used for flow measurement can be locked when the flow meets the design requirements. It can ensure the constant flow and fully realize the hydraulic and thermal balance of the system.

2. The valve is composed of valve body, center line butterfly valve, driving device, bolt, etc.

3. Rotate the hand wheel and the valve stem to drive the valve disc to rise or fall to realize flow regulation.

Valve features

1. The structure is reasonable and compact, the volume is small, the appearance of the valve body is barrel or streamline, and the shape is beautiful.

2. Small opening and closing torque and safe and reliable sealing.

3. It has good flow characteristics, can reasonably distribute the flow and solve the problem of hydraulic imbalance in the pipe network.

4. It can accurately adjust the pressure drop and flow and improve the medium flow state in the pipe network, so as to achieve the purpose of medium balance.
