General:
SDF can be used as actor of automation system in water supply system, fire control system,
Water spray system and for pneumatic hydraulic and food machine application.
Characteristics:
· Suitable for air, clean water, steam and ≤ 4° E viscosity machine oil.
· Coil type:
AC: 24V, 36V, 110V, 220V
DC: 12V, 24V
· Temperature of medium -25º C to 130º C.
· Max Working Pressure: 20bar.
Versions with UL/CUL approval can be supplied to order.
Installation:
The valve should be installed in horizontal pipe line under vertical position. The flow direction must be in the arrow direction.
The supply voltage must meet rated input voltage shown on the label of the coil. Coils taking away from valve when energized in coils is forbidden.

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.
