Description & Features

Pressure Seal Check Valves are ideal for high pressure steam, liquid, catalytic reformers, hydro crackers and other tough services. In the tough world of High pressure, High temperature valve applications, Pressure Seal Check Valve continue to provide a wide range of industries with a safe, leak free, pressure containing boundary. These valves are unidirectional and restrict flow from opposite direction. These are best suited for moderate velocity conditions. Check valves are normally designed for horizontal flow condition, but can also be installed in vertical pipeline, but in vertical pipeline, the flow shall be in upwards direction and under the disc

● Only one sealing face is designed on the valve body and valve disc,

● Full stellite overlay seat sealing surface

● Good for manufacturing process and easy to maintain.

● Use flexible and woven graphite collaboration type packing.

● Absolute bonnet joint leak proof.

● Optional by-pass design.

● Optional designed with a Damping Cylinder.
