The most widely used design in the refrig- eration industry, the basic “Y” design of this check valve reduces pressure drop to a very
low level. Seat insert is made of durable Teflon insuring positive shut-off. Features secondary seat backing-up the primary seat to assure proper seal even after extended service. Internal parts easily removed for soldering. Forged brass body. Rated up to 700 psi.
Unrestricted flow line and angle shut-off valves. Balanced bearing surfaces and polished stem heads eliminate wear and assure smooth operation. Metal diaphragms backseat metal-to-metal when the valve is fully open. Can be soldered into the line without disassembly. Fur- nished with “Comfort-grip” nylon handwheel. Rated up to 700 psi.

Globe check valves feature the time-proven piston construction simplified for easy reassembly after soldering. Teflon seat inserts and special bonnet gaskets permit these valves to be used in service
temperatures as high as 400°F. All valves are forged brass construc- tion in the low pressure drop “Y design”. May be installed in any position except upside down. Bonnets are loosely assembled after testing to ease disassembly for soldering. Rated up to 700 psi.
Streamlined flow and minimal pressure drop in an extremely compact design. Inclining the seat to a 70° angle minimizes turbulence to help obtain
maximum capacity. Special bonnet gasket and Teflon seat inserts permit the use of these valves in service temperatures as high as 400° F. Metal-to-metal alignment assures perfect seal. The OD dimensions will accept solder coupling of the next line size. Rated up to 700 psi.
All purpose ASME refrigeration relief valves for in- line installation. Heavy duty brass construction with Teflon valve seats to assure position re-seating in high or low temperature application. Rated up to 700 psi.
Forged brass diaphragm packless globe valves with inclined nylon seated stem assembly for maximum flow and minimum pressure drop. Can be soldered into line without disassembly. Rated up to 700 psi.
