Sporlan Solenoid Valves for Secondary Coolant Glycol
Description
A new line of solenoid valves to control secondary coolants has been developed for supermarket systems. These fluids include propylene glycol, ethylene glycol, Pecasol 50, Dynalene HC-40, and others. Parker!ˉs valve is the only valve designed to meet the requirements of both medium and low temperature applications encountered in supermarket applications.

Minimum Pressure Drop
In order to achieve good heat transfer through a coil surface, minimizing pressure drops throughout the system is critical. Parker secondary coolant valves do not require a minimum pressure to operate.* This is because of the valve!ˉs unique !°hung diaphragm design. Other pilot operated valves require some minimum pres-sure drop to open the diaphragm or piston. This minimum pressure drop is a pressure loss, and means less pressure available at the coil. When using Parker!ˉs secondary coolant valves, valve size can be maximized, minimizing the pressure drop.
*The 34E24C2-R1021E is pilot operated and requires a minimum of 5 psi. It uses the AF-4 series coil.
