Pneumatic gate valve made of galvanized steel with a diameter of 200mm.When placing an order, VERY SIMPLE TO DECLARE WITH WHICH CEW THE gate valve is to be 230V or 24V.Opening and closing automatically, the extraction is always concentrated on the connections, extraction points or on the machines currently in use which maximizes the compression in the installation and reduces energy consumption.The gate valve is opened and closed by one or two actuators depending on the diameter. The actuator is operated by a solenoid valve connected to the machine or to a switch. With a microswitch mounted on the damper, for example, the fan can be turned on or off when the damper is opened or closed.TECHNICAL DATA:A: 699mmB: 463mmC: 125mmD: 276mm
