Swing Check Valves
Backflow prevention – Automatic operation
WHY SWING CHECK VALVES?
Check valves are self-acting safety devices — they require no operator input. A swing check valve uses a hinged disc that opens under forward flow and snaps shut the instant flow reverses. They protect pumps, compressors, and pipeline equipment from damaging backflow and water hammer.
IDEAL APPLICATIONS
- Pump discharge lines in water treatment plants
- Boiler feed water lines (IBR-compliant)
- Ballast and bilge systems in marine installations
- Oil and gas pipeline protection
- Sewage and effluent treatment systems
KEY SELECTION PARAMETERS
SWING CHECK VS DUAL PLATE CHECK
For larger pipe diameters or high-velocity systems, a Dual Plate (Wafer) Check Valve is preferred — it closes faster, reduces water hammer, and takes up less face-to-face space than a swing check design.
Butterfly Valves
Large bore – Lightweight – Space-saving
WHY BUTTERFLY VALVES?
Butterfly valves deliver a cost-effective, space-saving solution for large-diameter pipelines. Their disc rotates 90° to open or close, offering fast operation and moderate flow control. Concentric, double-eccentric (high-performance), and triple-offset designs are available for progressively tighter shutoff requirements.
IDEAL APPLICATIONS
- Water supply and cooling water systems (large bore)
- HVAC air handling and ductwork
- Cargo handling pipelines in dockyards
- Firefighting and sprinkler systems
- Municipal water treatment infrastructure
KEY SELECTION PARAMETERS
Y-Type Strainers
Inline filtration – Protecting downstream equipment
WHY Y-TYPE STRAINERS?
A strainer is not a valve in the traditional sense, but it is an indispensable companion in any piping system. Y-type strainers filter out scale, rust, weld spatter, and debris that would otherwise damage pumps, meters, valves, and heat exchangers downstream. Always install a strainer upstream of critical equipment.
IDEAL APPLICATIONS
- Upstream of pump suction inlets
- Before flow meters and control valves
- Cooling water and process water lines
- Steam condensate return lines
- Chemical dosing and injection systems

Quick Decision Table
Quick Decision Table
| Application Scenario | Recommended Valve | Reason | Avoid |
|---|---|---|---|
| Full isolation of high-pressure oil pipeline | Gate Valve | Full bore, minimal pressure drop, tight seal | Globe (higher ΔP) |
| Emergency shut-off on gas line | Ball Valve | Quarter-turn, fast operation, bubble-tight | Gate (slow operation) |
| Steam flow control in boiler | Globe Valve | IBR-compliant, excellent throttling | Ball (poor throttle) |
| Pump discharge backflow prevention | Swing Check Valve | Automatic, no actuator needed | Gate / Globe (manual) |
| Large-diameter cooling water system | Butterfly Valve | Compact, lightweight, cost-effective for large bore | Gate (heavy, expensive at large sizes) |
| Protecting pump from debris | Y-Type Strainer | Inline filtration, easy to clean | Any valve alone (no filtration) |
| Cryogenic LNG service | Ball Valve (cryogenic trim) | Rated to -196°C, compact, reliable at low temp | Standard cast iron valves |
| Corrosive chemical service | Ball / Globe Valve (SS 316 / Alloy) | Corrosion-resistant metallurgy | Carbon steel WCB valves |
