1、 Overview of Electric Clamp Ball Valve Products
The Q971F/PPL electric clamp ball valve of Shanghai Yuhu Company is composed of an angular stroke electric actuator and an ultra-thin ball valve body, also known as an electric ultra-thin ball valve. Mainly suitable for situations where two positions are cut off and adjusted. The connection between the ball valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system and does not require a separate servo amplifier. It can be controlled by inputting a 4-20mA signal and a 220VAC power supply. Electric clamp ball valves have the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable action, etc. Electric ultra-thin ball valve refers to the characteristics of Italian products. Compared with ordinary ball valves, it has significant advantages such as short structural length, light weight, easy installation, and material saving. In addition, the valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. Equipped with fire-resistant structure, it can still operate reliably and have good sealing in case of fire.
