NACE REQUIREMENTS
Materials conforming to Nace MR-01-75 can be offered for highly corrosive sour service.

ELASTOMER SEATS
For tight shut-off in low pressure and for highly corrosive applications.

OXYGEN SERVICE VALVES
Specially designed valves for oxygen service with non-frictional contacts on seats and materials supplied completely decreased.

CRYOGENIC (LOW TEMPERATURE SERVICE) VALVES
Low temperature service tests and valves supplied with suitable materials for non-jamming operations under low temperature.

FIRE SAFE VALVES
Applied to soft seated valves - these valves are suitably designed with dual seating to minimize leakage through seats in case of fire conditions in or outside the line. Also these are supplied with anti-static devices to prevent sparking due static creation during operation.

VACCUM SERVICE
These valves are specially designed to ensure vacuum conditions in the line and gland sealing is provided by way of water passage to ensure no drop in vacuum conditions through gland areas.

HIGH TEMPERATURE VALVES
Valves for very high temperature service upto 1500 deg. cent. can be supplied with water cooling arrangement for seats and body. Through a jacketing on the body and internals. Further refractory lining can be provided.

FABRICATED CONSTRUCTION VALVES
Valves in sizes larger than 600mm (24”) can be provided in fabricated steel construction thus ensuring a considerable weight reduction.
