Refrigerator Automatic Pressure Control
General:
1. YK is used for pressure control or pressure protection. When the system reaches the set point, the switch turns on/off automatically.
2. Optional automatic reset, high pressure manual reset as well as low pressure manual reset.
3. Adjustable pressure and pressure difference setup with scale instrument.
4. Suitable for HFC, HCFC, compressed air, water and oil.
5. M12× 1.25 connection.
6. Temperature of medium: - 20º C~+120º C; Ambient temperature: - 20º C~+70º C.
Ordering Information:
1. Standard parts refer to connection size & minimum flow factory setting.
2. Flow rate listed in the technical data is reference for product selection only.
3. If you have special requirement, please contact STF.

Shanghai Thermostat Factory Co., Ltd. is a professional manufacturer of refrigeration and air condition auto-control unit. We have more than 60 years history in this industry.
In 1985, STF cooperated with ALCO to produce T series expansion valves. We were the only Chinese company having the mixed infusing technology in expansion valve production. In 1993, Shanghai Johnson Controller Co., Ltd. Was established by us and Johnson to produce YK series controllers. In 1996, FDF-M diaphragm solenoid valve was certificated as National Grade New Product. As a high-tech enterprise, we get innovation fund from the government.
Our main products include solenoid valves, thermostatic expansion valves, sight glasses, filter dryers, pressure controls, pressure difference controls, temperature controls. We have gained approval for our quality control system in relation to international standard ISO9001: 2008. UL/cUL\CE & CQC approval can be supplied to order.
Products are widely used by Carrier, YORK, Trane, Dunhambush, McQuay, Mammoth, HANBELL, RefComp, Midea, Gree etc. And exported to America, Europe, Australia, Africa, Korea, Hong Kong, Philippine and Taiwan.
We stick to the development of specialization, give the best solution of localization and keep advanced in technology by continual innovation. We are always pursuing to be a leading enterprise in our area.
