Special Features: The cast iron swing check type Reflux valves are strictly manufactured as per 15:5312 part-1. These Valves are generally used to maintain flow of water in only one direction and stop the return flow of the water. They are self-operative by pressure only. These valves are used in water main lines all over the world, especially in hilly areas. These can be fitted in horizontal or vertical positions. These valves are ISI-marked. All the major components of these valves of manufactured in our factory right from casting to the final testing. The flanges of these valves are normally drilled as per 151:1538 but any type of drilling like BS: 10, DIN, ASA, etc. can be provided These valves can be supplied with door faces either of metal or rubber as per requirement

We can also provide external bypass arrangements with these valves where designs are tested as per IS:5312 as follows:

Text Pressure body 25(kg/cm.sq)
Seat 15(kg/cm.sq)10(kg/cm.sq)
