Compact Apollo® Valves 4SG double checks are built to take up less valuable real estate, but they are not short on safety. The 4SG Series is approved by the USC FCCC&HR for both horizontal and vertical-up orientations. They are also ASSE, CSA, UL, and FM approved.
Sized from 2-1/2 to 8 in., new Apollo 4SG assemblies feature grooved end connections that reduce weight and length. They also allow for the use of lightweight grooved-end butterfly valves as shut-offs. OS&Y or NRS gate valves, with either grooved or flanged end connections, are also available.
Designed, built and tested in the U.S., Apollo 4SG devices employ patented modular check making seat replacement easy. They also feature reversible EPDM seat discs. The individually accessible check modules make service fast and easy while the valve remains in-line. No special retaining clips or tools are needed. Top-mounted test cocks assure easy testing.
Their epoxy coated ductile iron bodies resist corrosion for long service life in a variety of applications such as irrigation systems, domestic water service and commercial and industrial plumbing systems. Fully-approved double check detector assemblies are also available for fire sprinkler applications.
Maximum working pressure for the 4SG Series is 175 PSI; operating temperature range is 33°F to 140°. They are manufactured in the USA in ISO 9001:2001 registered facilities, ensuring high quality and excellent availability.
