Hydraulic Override Check Valve

Remote operated lock open check valve, developed for application during well intervention work

 

Project objective

Development of remote operated lock open check valve for application during well test and well intervention operations

The remote operated lock open check valve is designed to be used during well test and well intervention operations to prevent any unintended fluid return to cement unit or any other high pressure / high volume application, avoiding getting contaminated fluid back. The unique design of the check valve makes it the best suitable choice for high pressure operations in the marked. The valve is designed such as the flapper, seat and seal area will be protected when it is in locked open mode, making it ideal for pumping operations where you have fluid with high solid and proppant content.
