Gate valves in Bangladesh

Use

Gate valves are for fully open or fully closed service with low pressure drop. For throttling use a globe or butterfly valve instead.

Body material

Cast iron or ductile iron for water and fire lines; carbon steel (WCB, A105) for steam, oil and higher pressure; stainless steel for corrosive or hygienic service.

Stem

Rising stem (OS&Y) shows at a glance whether the valve is open: required on many fire-protection systems. Non-rising stem saves height in pits and buried lines.

Seat

Resilient (rubber-encapsulated) wedge for drinking water and tight shut-off; metal wedge for steam and high temperature.

Standards

API 600/602, BS 5163, EN 1171, ASME B16.10 face-to-face and B16.5 flanges; UL/FM listed valves for fire systems on request.

Price depends on size, pressure rating, body material (cast iron, carbon steel, stainless steel) and brand. Send the size, rating, connection and quantity and we quote within 24 hours.

Gate valves give a straight, full-bore flow path and tight shut-off; butterfly valves are lighter, cheaper and quicker to operate in large sizes and can throttle. For fire lines and steam, gate valves are common; for large water lines, butterfly valves.

For thick media such as slurry, pulp, sludge and ash, where the sharp gate cuts through solids that would jam a normal valve.
