We designed and manufactured the pilot type balance gate valve for American Kirk oil field fracturing equipment company.It is the first high pressure pilot type balance gate valve in the global market. The structure of this valve is different from traditional large size high pressure valve. It is structure compact and small size valve.The torque is only ¼ of normal valve with same diameter and same pressure. The weight is only 30% of normal valve. the cost of this valve is comparatively lower than normal valve. This design is a great innovationfor high pressure large size gate valve. 

Nominal diameter:4-1/16 ″~ 7-1/16 ″

Working pressure:10000~20000 PSI
