Needle Valves with mechanical adjustment
NV type valves are designed for fine-adjusting of gas flow and air flow 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, 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.
