Y-Type strainers are classed as a permanent strainer of a Y-configuration consisting of an integral cast, forged or fabricated body housing a cylindrical strainer element which is usually called a “screen”. The screen is located within the Y-pattern body and access is via a branch cover. T-Type Strainers can be installed both in the horizontal and vertical positions without any effect on performance providing the screen is installed in the downward position to assist draining and cleaning operations.
Y-Type strainers are very versatile and are used in a wide range of applications where protection of major capital equipment is required such as pumps, flowmeters, control valves, steam traps, heat exchangers, chillers, spray nozzles, relief valves and regulators.
Two types of cover are available on standard GFSA Y-Type strainers:
- Increased Safety Cover
The increased safety cover was primarily developed for the gas industry and prevents the cover from being removed before the unit has been vented and all internal residue pressure removed, providing the optimum in operator safety.
Sizes range: From ½” (15mm) to 2” (50mm) n.b. for forged units, ½” (15mm) to 14” (350mm) n.b. for cast units and 1” (25mm) to 24” (600mm) for fabricated units.
Pressure ratings: Available from 125LB to 2500LB
