A Slab Gate Valve as called Flat Gate Valve is a type of closure device for parallel slide valve of a gate. Slab Gate Valve are widely used in oil, natural gas long distance pipeline and gas filed.
There are many types of flat gate valve:
As to different operation, there are manual flat gate valve, pneumatic actuator flat gate valve, electric actuator flat gate valve and so on.
For different usage, there are through concuit flat gate valve, without through concuit flat gate valve, Oil flat gate valve and gas flat gate valve.
Accoding to closure pieces, there are single disc flat gate and double disc flat gate valve.
Meanwhile, there are rising stem slab gate valve and non rising stem slab gate valve
So how to choose the right flat gate valve is very important to us. General speaking, we have the following conclusion:
Single-disc or Double Disc are both suitable for Oil and natural gas transimission pipelines. If it is needed to clean the pipeline, a through concuit slab gate valve is most suitable.
Non through concuit slab gate valve are suitalbe for the pipeline and storage equipment of refined oil.
API6A Through Concuit Slab gate valve with floating valve Seat are widely used for oil and gasproduciton wellhead devices.
Soft seat slab gate valve is used for gas transimission pipeline in city.
Non througn concuit slab gate valve are widely for Urban Water supply project.
