SG+ Stainless Steel Sight Glasses - Exceptionally reliable in any environment

• Laser welding & steel-glass joining provide very reliable tightness and strength that can bear 5 x >> MWP.
• The stainless steel valve body provides long-term anti-corrosion properties.
• The components and construction reduce the thermal sensitivity of SG+, thereby minimizing the risk of overheating when brazing.
• The Max Working Pressure is improved up to 46 bar (667 psi) for all the valves in SG+ platform.
• SGN+ are available for R410A thus replacing the SGN and SGH models reducing the amount of code numbers required for stock..
• SG+ is much easier to observe with 14% greater viewing area when compared to the SG version.
• No 'Black Eye' (no influence from dirt in the system).
• Available with optional plastic cap offering extra protection to the sight glass.
• SG+ is available at the same pricing level of the previous SG range giving great value for money.

• SGN+ is mounted in the liquid line to monitor the moisture content.
• SGRN+ is mounted in oil receiver or compressor to monitor the moisture content.

• SGM+ is mounted in the liquid line to monitor the refrigerant and can be used to see;

- If subcooling is insufficient (bubbles)

- If there is acid in the system (oil discoloured from light brown to black)



The code numbers remain almost the same. The "-" of the previous SG versions is replaced with an "F" for the new SG+ versions e.g. 014-0171 becomes 014F0171.



This, however, is not the case for SGH as they are now replaced by SGN+ as indicated in the table above. The introduction of the SG+ will be phased in over the coming months with a safety stock of the SG being gradually reduced as that of the SG+ is increased.
