Overview:
Goggle valve (Blind valve) is a gate valve that cuts off gas medium by manual, electric, pneumatic or hydraulic operation. It is generally divided into electric blind valve, hydraulic blind valve, closed plug valve and electric open blind valve. Blind valve consists of left and right valve bodies, telescopic mechanism, fan-shaped valve plate and electric push rod I for driving the valve plate and electric push rod II for clamping and releasing.
Features:
The rubber sealing ring is embedded in the valve plate, which has the characteristics of high temperature resistance, good sealing performance, easy replacement and long service life.
This valve can be remotely controlled by a single unit or by multiple units connected to the network. It is especially suitable for cutting off harmful, toxic and flammable gases, and is also suitable for the blind plate of the pipeline terminal to shorten the maintenance time or facilitate the connection of a new pipeline system.
It has the characteristics of novel structure, light weight, small size, convenient operation, rapid action and reliable gas cutting performance.
