Electric ITALY Ball Valves

Q971F / PPL electric clamping valve consists of angular stroke actuators and ultra-thin ball valve bodies, also known as electric ultra-thin ball valves. Mainly suitable for two-position cut, adjust the situation. The connection between the ball valve and the actuator adopts the direct connection mode. The electric actuator has built-in servo system. It can control the operation without additional servo amplifier and input 4-20mA signal and 220 VAC power supply. Electric pinch ball valve has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable operation. Compared with ordinary ball valves, electric ultra-thin ball valves have the advantages of short structure length, light weight, convenient installation and material saving. In addition, the valve seat adopts the elastic seal structure, the seal is reliable, the opening and closing is easy. Fireproof structure which can be operated reliably and has good sealing ability in case of fire
