Thermal Expansion Valves
Applications
• Series 935 valves are applied as temperature controls.
• Applications include:
- Desuperheating of discharge gas on compres sors. In this
case bulbs are mounted on the high pressure outlet of
the compressor
- Control of compressor oil temperatures
• Series 935 valves shall not be used to control superheat
Features
• Modular design for economical logistics and easy assembly
and servicing
• Very good stability because of the large forces generated by
the large diaphragm diameter
• High-quality materials and processes for high reliability and
long lifetime
• Combinations of different charges with various orifice
springs cover a very large application range
• PS: 46 / 31 bar with XB / XC power assembly
• TS: -45 ... +65°C
• No CE marking according art. 3.3 PED 97/23 EC
• Non-standard connection sizes see last page of this chapter
