Types of Control Methods
Diverting Type
This method controls the flow rate to the cooler based on the temperature of the fluid entering point A, in order to maintain a constant temperature at point X.
Mixing Type
This method regulates the mixing ratio between the fluid entering point B and the fluid cooled through the cooler, based on the temperature of the fluid at B, to maintain a constant temperature at point Y.
Port Symbols and Names
A: Engine or Condenser
B: Bypass
C: Cooler or Cooling Tower
Note: Please specify the control method when placing an order.

Features
Compact and lightweight, yet the element provides powerful output.
No external power such as electricity, hydraulic, or pneumatic pressure is required—making it economical.
Models S(M)FH4, S(M)FH5A, and S(M)FH6 can be maintained, inspected, and have elements replaced without removing piping.
In emergencies, manual operation can prevent overheating of the fluid.
Can be installed in both horizontal and vertical piping. However, for maintenance and inspection purposes, it is recommended to install upright (as shown on page 158).
Operating characteristics are not affected by ambient temperature.
Fluid leakage from sliding parts is minimal.

Nominal Diameter Selection
The nominal diameter is usually matched to the counterpart flange. However, when determining it by calculating the pressure loss (sizing ΔP), a flow rate vs. pressure loss chart is used. Normally, the sizing ΔP is selected to be 0.03 MPa or less.
Assembly Orientation (Viewed from Above)
For models S(M)FH5A, S(M)FH4, and S(M)FH6, please specify the orientation of ports B and C relative to port A when placing your order. If no specification is provided, the product will be delivered in the STANDARD (normal assembly) configuration.
