Description
HD Y-Type Strainers are used for filtering out the dirt, rust, and other debris in the water flow protecting the piping equipment such as pumps, meters, valves, and other equipment in the piping system. All strainers are equipped with a retainer cap which allows easy access to the stainless steel screen for cleaning. Strainers should be installed horizontally with the cap facing downwards with access to remove the basket/ screen. Direction of water flow is marked on the strainers.
INSTALLATION
HD Y-Type Strainers are supposed to be horizontally installed with flow direction as marked on the valve and basket/screen facing downwards. The Strainer can also be installed vertically with downward flow and the screen element pointing downward. The Strainer must be installed in an area not subject to physical damage. When corrosive atmospheres and/ or contaminated water supplies are present, it is the owner’s responsibility to verify compatibility with the Strainer and associated equipment. HD Y-Type Strainer flanges are Ductile Iron ANSI B16.1, Class 125, with a maximum water working pressure of 300 psi (20.7 bar). ANSI B16.42, Class 125 flanges are not compatible with ANSI Class 250
or Class 300 flanges. HD Y-Type Strainers described herein must be installed and maintained in compliance with this document and with the applicable standards of National Fire
Protection Association (NFPA), in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices.
CAUTION
Y-Type Strainers must be inspected, tested and maintained as instructed above, in addition to the requirement of NFPA, or as per requirement of authority having jurisdiction. The owner is responsible for the inspection, testing and maintenance of the system.
