Description

Usability Of Delta-Elektrogas NV Needle valves

Delta-Elektrogas NV Needle Valves with mechanical adjustment are designed for fine-adjusting of gas flow and airflow in industrial combustion processes. Valves are operated manually using an Allen key to set the precise fire rate of the burner. All components are designed to withstand any mechanical, chemical, or thermal condition occurring during typical service. Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing, and resistance to corrosion of the components.

2011 – Elektrogas range celebrates 30 years in the market, with a product portfolio that now includes control valves, filters, gas regulators, servomotors, combustion controllers. Elettromeccanica DELTA, with its brands Elektrogas and Deltapumps, is a proud manufacturer of safety and control products for gas firing systems and fuel oil appliances, successfully installed in more than 60 countries in the world.

 

Features

Valves are made of aluminum, with a wide range of threaded connections.
Suitable for use with air and non-aggressive gases according to EN 437. For heated air or
aggressive gases, a special version is available.
Valves are operated manually using an Allen key to set the precise fire rate of the burner.
All components are designed to withstand any mechanical, chemical, or thermal condition
occurring during typical service. Effective impregnation and surface treatments have been used
to improve mechanical sturdiness, sealing, and resistance to corrosion of the components.

Applications

The valve is provided with a tapered plunger that can be adjusted sensitively with an Allen wrench,
turning the screw counterclockwise increases flow, then a locking nut allows it to hold the
regulation. A plastic cap hides the adjustment to avoid tampering with the setting.
