However, when an abnormal pressure is introduced which upsets the equilibri- Pilot Control Valve um, another effect may be accomplished. The principle upon which the 180 Solenoid Pilot Control influences the expansion valve action is by the creation of a pressure under the valve FEATURES diaphragm, which is higher than the bulb pressure. -

Page 11: Installation
Bulletin 30-21 – Page 11 SPECIFICATIONS On double-ported thermostatic expansion valves, such as Sporlan’s Types V and W, the chance of dirt causing leakage MKC-2 Coil is increased since either port could be partially blocked open. If this occurs, the leakage would be even greater since both Type 180 Standard Coil Ratings ports would leak because the seating discs operate on the... -
