Liquid Injection Valves Series 935
Exchangeable Power Assemblies and Orifices
72
Applications
• Series 935 valves are applied as temperature
controls. Applications include:
- Desuperheating of discharge gas on compressors.
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 is attained 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: 31 bar, TS: -45 ... +65°C
• No CE marking according art. 3.3 PED 97/23 EC
• Non-standard connection sizes see page 76
