Long Type Single Door Wafer Type Check Valve
Long Type Single Door Wafer Type Check Valve
Single-plate wafer check valves are also called swing type that performs the same with swing check valve with much less cost. The Long type Single plate wafer type check valves, normal material of it is stainless steel (CF8/CF8M) and WCB.
The Long type single plate check valve with long working life (It should be used under standard installation and normal using procedures), stable performance, simple structure, the lightweight and subtle pressure difference between opening and closing. The difference between Long type single door check valve and short type single door check valve is the thickness of face to face. Single plate wafer type check valve with Long type is a valve which discs closedown quickly and low water hammer pressure, applicable for and easily installed for vertical and horizontal pipelines.
There are various types of check valves available for water and wastewater applications. They work in different ways but serve the same purpose. STV offers a wide range of twin disc wafer check valve, single door check valve(short,long pattern), spring disc check valves and 3-pcs check valves. Please send the inquiry to STV below for more information.

More Knowledge about STV valve:
STV Single plate wafer type check valve with Long type smooth flow passageway and small fluid resistance; flexible action and good sealing performance; narrow valve travel and small closedown impact; Integrated structure, simple and compact; Long service life and good reliability. Because of Long type Single plate wafer type check valve thickness is larger than short type single plate check valve, so the pressure can afford larger than it. For example, the long type has class 300LB, but short type only has 150LB
