Didtek Cast Trunnion Ball Valve

Didtek Cast Trunnion Ball Valve designed the Side-Entry Trunnion-Mounted Ball Valves to assure bi-directional sealing of the valve with two independent floating seats. The design of these seats minimizes the torque required to operate the valve without losing the sealing power. This power is assured by zero differential pressure to the valves maximum rated pressure. In addition, these repairable valves are manufactured to seal off both seats at the same time and to allow bleeding of the entrapped cavity pressure(DBB) with the ball in the closed position. The DBB feature allows for verifying that the seats are properly sealing.

DIDTEK DIN Globe Check Valve

Didtek DIN Globe Check Valve structure is similar to globe valve,but the connection of stem and disc are not fixed.The globe check valve could run globe valve fuction when the stem drops and compresses the disc on the seat,while when the stem rises up,it could work as a check valve.When we need to install both globe valve and check valve on the pipe at the same time,or with limited installation area,the globe check valve would be the best choice as it could save installation cost as well as space.
