General Description: 
Non-rising stem gate valve is used where vertical space is limited or underground. The stem is threaded into the gate. As the handwheel on the stem is rotated, the gate travels up or down the stem on the threads while the stem remains vertically stationary. This type of valve has a pointer indicator threaded onto the upper end of the stem to indicate the position of the gate.

General Description:
Leakage from the valve gland (stem packing) is often a problem for environmental protection & sometime it is quite dangerous if such leakage is from a hazardous fluid or gas. FLOWTEK bellow sealed valves are designed with a bellow cartridge which welded to the valve bonnet and stem, so that when the stem up & down movement makes the bellows expands & compress. Therefore there is no sliding or rotating seals through which process fluid can leak.

General Description:
Pressure sealed gate valves are designed for high temperature, high pressure, services mainly encountered in nuclear and fossil fuel power plant. Compare with bolted bonnet valves, Flowtek’s pressure sealed gate valves are less complicated and can provide absolute excellent seal service with minimum maintenance.
