Description

Watts Series 601S Check Valve 3/4" Same as No. 601 Series, except with solder ends. Sizes: 1 /2 ", 3 /4", 1" (15, 20, 25mm) Maximum pressure/temperatures: 15 psi (1 bar) Steam WSP @ 250° F (121° C), 400 psi (27.6 bars) WOG non-shock @ -20° F (-29° C) to 100° F (38° C). Conical brass disc for full fluid flow. PTFE seat. Install in horizontal or vertical position. (Consult factory for proper use in vertical installations) Low pressure drop equivalent to a swing check. Stainless steel guide rod and spring. Silent operation. APPLICATIONS: Series 600 check valves will efficiently perform all of the functions of a swing check or vertical lift check valve, and at the same time operate silently to prevent the effects of water hammer. These valves are not suggested for installation in sewage ejector piping. ***WARNING: Do not use for reciprocating air compressor service. ***This valve is designed to be soft soldered into lines without disassembly using a low temperature solder; 420°F (216°C). Other solders such as 95/5 tin antimony 460°F (238°C) or 96/4 tin silver 430°F (221°C) can be used. However, extreme caution must be used to prevent seat damage. Higher temperature solders will damage the seat material. ANSI B16.18 states that the maximum operating pressure of 50-50 solder connections is 200 psi (13.8 bars) at 100°F (38°C), and decreases with higher temperatures. Apply heat with the flame directed AWAY from the center of the valve body. Excessive heat can harm the seats.
