Linear modulating valves Modulating valves LMV are used in combustion processes that require linear adjustment of air or gas flow. The flow varies proportionally to the opening angle of inner mechanism, therefore flowrate is very predictable. The valve can be operated with stage control (3-point, MZ3 servomotor) or with continuous modulation (analogue signals, MZ5 servomotor). […]
Burner control systems CF burner control system is a device that ignites and monitor the flame in the industrial gas burners with continuous service, with self-test function of the detection circuit. CF is available with single control or double control for valves. Flame detection can be done via a single rod, two rods or UV […]
Pressure relief valves VS type is a pressure relief valve designed to reduce temporary pressure peaks in burning appliances. The shutting-off of automatic valves or non-tightly closing of regulators can cause pressure increase; by releasing that overpressure in a relief line, VS valve enables the system to work properly again.
Tightness control LD tightness control is designed to verify the absence of inadmissible leaks in gas trains composed by automatic shutoff valves. The check can be performed before the ignition of the gas burner or after its stop. This device is used in industrial firing processes and in forced draught burners (when power is higher […]
Gas pressure regulators with filter The R… type products are pressure regulators for gaseous media, suitable for all types of gas consuming systems. RF is a regulator with an integrated 30-micron filtering element. All models are equipped with compensation diaphragm to assure high accuracy and are designed to perform lock-up function. Max inlet pressure 500 […]
Gas pressure regulators with filter and safety shut- off valve The R… type products are pressure regulators for gaseous media, suitable for all types of gas consuming appliances. RAG is air/gas ratio control (1:1) for combustion processes. It is provided with adjustable offset spring (+/-3mbar) and adjustable bypass. It is also usable as zero-pressure governor. […]
VSG type is a globe valve for gas suitable for inline installation and end-of-the-line mounting. The inner globe is manufactured with a full and straight gas passage that results in low pressure drop and limited generation of turbulence. VSG is usually supplied with manual lever but it can be operated by various actuators. Special versions […]
