Series CS
Check Stop Valves
Sizes:

⁄2",

⁄4", 1" (15, 20, 25mm)
Series CS check stop valves are designed for use at the hot
and cold water inlet supplies for mixing and tempering valves.
Series CS valves perform triple duty as: 1) isolation valves,
2) check valves, and 3) strainers. The union connections
facilitate service and maintenance of both the valve and the
strainer.
Series CS valves protect against cross flow of hot and cold
water in the system and provide isolation of the mixing or
tempering valve during servicing and maintenance of the valve
and strainer. The integral fine strainer protects the valve from
damaging dirt and other debris.
Features
• Performs triple duty as: 1) check valve, 2) shutoff
valve, and 3) strainer
• Check valve function protects against hot and cold
water supply cross flow.
• Shut-off function facilitates mixing valve service and
strainer maintenance
• Strainer protects mixing valves from dirt and other
debris
• Universal design eliminates left-hand/right-hand
confusion
