Overview1 / 3
Trusted Across Process Industries
Valves and engineered equipment from the AB Group supplied to leading oil & gas companies and government undertakings across power, steel and mining.
Product Overview
Compact Wafer Check Valves with Minimal Pressure Drop
FLOEC Dual Disc Check Valves are designed and manufactured as per API 594 and supplied in an extensive range of sealing — metal to metal, soft, and completely lined valves with diverse lining materials such as different varieties of rubber, PTFE / PFA and similar.
The dual disc design minimises pressure drop across the valve. Spring-loaded discs allow the valve to be mounted in horizontal or vertical directions. Very little space is needed for installation compared with swing check valves, and the valve is also lightweight and economical.
Offered in cast iron, S.G. iron, cast carbon steel, cast stainless steel of all grades, and high alloy steels like Alloy-20, CD4MCu, duplex, super duplex and Hastelloy. Sizes range from 50 NB to 900 NB and pressure ratings from ASME 150# to 600#.
Typical Applications
- Water & Cooling
- Pump Discharge
- Oil & Gas
- Chemical
- HVAC
- Power
