300X flanged check valve brass seat brass pipe stainless steel stem
to no back water
300x flow control check valve was composed bya diaphragm main valve, angle needle valve, ball valve, brass and
spring-loaded check valve, pressure gauge and so on. Spring-loaded
check valve installed in the control room formed at the entrance of
the control when the upstream pressure is greater than the pressure
control valve can be formed based on the time with field adjustment
This valve is used as an equipment to open and close pipeline and
set with a small solenoid valve to control the main valve to open
and close can carry out remote and local controls.
Easy installation and use ,no complicated electric sensing
mechanism with the control portion, uneasy to be failed, easily set
table. compared with the conventional valves,featuring a small
volume, alight weight, a small power, easy repair ,convenient, safe
and reliable use.
The pilot valve comes as a solenoid valve and then the solenoid
valve is opened,the upper cavity pressure of the diaphragm will be
reduced and the main valve is opened.the solenoid valve is closed
and so os the main valve.
valve is opened.the solenoid valve is closed and so os the main
There are normal open and normal close two types of solenoid
valve.the normally supplied is normal close one. An explosion-proof
type solenoid can also be allocated.
