As one of the leading pneumatic actuated carbon steel gate valve,Website: , motorized carbon steel gate valve manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service. Application of pneumatic actuated carbon steel gate valvePneumatic gate valve's performance is reliable, convenient to replace and maintain, be widely used to control all kinds of medium by petroleum,chemical,sea transportation department. Characteristics of pneumatic actuated carbon steel gate valve1, pneumatic gate valve equip with pneumatic actuator and handle wheel2, gate valve actuator used double cylinder structure, elevating power doubled comparing with single cylinder pneumatic gate valve.3, resolved single cylinder pneumatic gate valve's disadvantage- the gate stuck in the valve body, can not open.4, there is buffer gear to reduce the abrasion between gate sealing surface and valve body sealing surface caused by the piston downward impact when close the gate valve, can avoid the wedge stuck meanwhile.
