Range Designator

Crack Open Temperature Adjustment Range

Change to Full Open Across the Range*

L low 5 to 105 F (-15 to 40 C) 35 to 12 F (19 to 7 C)

X cross ambient 60 to 140 F (15 to 60 C) 25 to 12 F (14 to 7C)

S standard 90 to 140 F (30 to 60 C) 20 to 12 F (11 to 7 C)

H high 100 to 170 F (40 to 80 C) 25 to 12 F (14 to 7C)

V very high 160 to 230 F (70 to 110 C) 40 to 21 F (22 to 12 C)

* The temperature change necessary to bring the valve from crack to full open decreases exponentially from the low end of the Crack Open Temperature to the high end of the Crack Open Temperature in each range. Example: a valve with a S (standard) range actuator set to open at 95°F will require an approximate rise in temperature of 20°F to go full open. The same valve set to open at 135°F will require an approximate rise in temperature of 12°F to go full open.

FEATURES

Thermostatic actuated valves are typically used to modulate the water flow in response to a temperature signal and are used in a wide variety of industrial and commercial process control applications where water is used as a heat transfer medium. For example, this type of valve is used to maintain precise control of the temperature of hydraulic fluid in plastic injection molding equipment.

Actuation by temperature

For all Metrex Valve sizes, 2-Way and 3-Way

For Direct Acting and Pilot Operated valves

For fresh water and marine

Fully adjustable control within desired range

Self-operating

Available in a wide variety of sensing bulb styles

Optional open on temperature decrease (on most direct acting models)
