The characteristics of mining flame-proof electric ball valve products
1, the main structure by the explosion-proof electric explosion-proof electric ball valve actuator and valve connection, voltage is AC220V or AC380V, suitable for flammable and explosive occasions. 4 - can also be input 20 madc signal and power control of valve opening, realize the parameters such as pressure, flow, temperature, liquid level adjustment. 2, quick and convenient switch, as long as the sphere to complete the turn 90 ° full open or close the action, rapid opening and closing. 3, two-way seal, sealed performance is good. Seat adopts teflon material. Due to the floating ball valve ball is floating, under the effect of medium pressure, the fitness ball to generate a certain amount of displacement in the direction of outlet and press in the outlet seal surface, and the sealing force with medium pressure increases. The valve stem blow-out proof and anti-static structure design. 4, with ISO5211 actuator mounting flange used on platform. Convenient installation of electric, pneumatic actuators, save installation space.
