CONVENTIONAL CHECK VALVE

Description

The conventional check valve is usually used in combination with a conventional gas lift valve and a conventional mandrel. This valve can prevent gas and fluid from flowing back from tubing to the casing annulus. The default base material for this valve is 316L, and nickel based alloy materials such as MONEL and INCONEL can also be provided according to customer requirements.

Feature and Advantage

• Standard NPT thread can achieve multiple check valve connections to better prevent leakage

• INCONEL spring can withstand the harshest corrosion and temperature, enhance valve reliability, and extend valve service life

• Elastic sealing enhances the integrity of the valve

• Use below 302℉

Application

• Gas lift production

• Chemical injection
