VMH VMP SERIES
Safety shut off valves, slow opening and fast closing with hydraulic or pneumatic actuator The VMH type valve is a safety shut off valve for gaseous media operated by hydraulic actuator. It is suitable for gas blocking and releasing controls, as required in the main pipe of gas power burners, atmospheric gas boilers, industrial kilns and […]
Safety solenoid valves for air and gas, fast opening and fast closing type The VMR type valve is a fast opening solenoid valve that is normally closed. When the coil is not energized the spring works on the disc keeping the gas passage closed. When the coil is powered the valve opens. When power is switched off the […]
Safety solenoid valves for air and gas slow opening and fast closing The VML type valve is a safety valve that is normally closed, with fast or slow opening and adjustable rapid section for initial gas flow. When not in working position the spring works on the disc keeping the gas passage closed. When the coil is powered […]
Multiple safety solenoid valve for gas regulating trains The VMM type valve is a combination of two valves in an only compact and versatile valve housing. The first valve is a fast opening safety solenoid valve. The second valve may be a fast opening or a slow opening solenoid valve to adjust the gas flow, […]
EVRMNC EVRM6NC SERIES
Safety solenoid valves for gas with manual reset, normally closed The EVRM-NC type valve is a manual reset safety valve that is normally closed. When the coil is not energized the spring works on the shutter keeping the gas passage closed. Simply by energizing the coil the valve does not open. It is necessary to manually […]
EVRMNA EVRM6NA SERIES
MODEL/TYPE:The EVRM-NA type valve is a manual reset safety valve that is normally open.A manual operation is therefore necessary to open the valve and set the mechanism consenting to maintain this state. The powering by means of line current and/or condenser discharge, induced by the leakage detector, causes tripping of the mechanism and consequent closing of the gas passage. If energizing of the sensor persists due to the presence of gas, the valve remains under power and does not
VF VFH SERIES
Butterfly valves for air and gas VF and VFH butterfly valves are designed for regulation and control of air and gas flow. Valves can be operated manually using a lever (to setup the high-fire rate of the burner) or automatically using a servomotor (modulating or staged control) or a solenoid actuator (two-stage control). The setting can […]
VRA VLA VTA SERIES
Solenoid valves for combustion air regulation The VRA/VLA/VTA types are normally closed solenoid valves for cold combustion air regulation. When the coil is not energized the spring works on the disc, keeping the adjusted minimum passage of air. When powering the coil the valve opens, moving the disc to the maximum open position. When power […]
SR SL ST SERIES
Solenoid actuator for butterfly valves Solenoid actuators are designed to operate VF and VFH butterfly valves. When the coil is not energized the inner spring pushes down the plunger and, by means of a gear mating, shifts the connected valve to the minimum opening position. When the coil is powered the plunger moves up fast (SR) […]
Servomotor for butterfly valves Servomotors MZ are designed to operate VF and VFH butterfly valves. They consist of a multi-stage spur gearbox with DC motor, driven by an electronic control unit. This allows a high torque and adjustable running time. MZ3 type is suitable for basic adjusting position, operated by cams connected to driving shaft. MZ5 […]
Gas filters Filters for gas pipelines with very high holding capacity of dust and impurities, suitable for protection of devices installed downstream. The filter cartridge is a steel supported frame covered with a high performance nonwoven made of polypropylene fibres, which satisfy the stringent requirements of Fire Class F1 according to DIN 53438 and thus […]
Proof of closure switch The PCS is a mechanically activated switch for monitoring the position of the valve plate. This device can be fitted to valves and actuators. It is designed in accordance with norm EN161 to detect the closed status. The compact, robust and functional design permits a simple and quick installation even on […]
The PSG 901 is an adjustable pressure switch for monitoring overpressure of air and non-aggressive gases (families 1-2-3 EN437).
The pressure switch is available in different pressure ranges, all with male threaded connection G1/4. Special versions are available for use with aggressive gases.
The compact, robust and functional design permits a simple, quick, and essentially maintenance free installation.
