Air and gas butterfly valves

Butterfly valve series BSV

The butterfly valves of the series BSV are DVGW approved to the Norm EN 161 with CE product identification number.

They are suitable to be used on residential and industrial combustion systems. They are particularly suitable for both manual and automatic control of gases belonging to the first, second and third family and of air.

Installation with two threaded flanges from Rp 3/4 to Rp 2.

Batterfly Valve Series BFV

The butterfly valves of the series BFV are DVGW approved to the Norm EN 161 with CE product identification number. They are suitable to be used on residential and industrial combustion systems.

They are particularly suitable for both manual and automatic control of gases belonging to the first, second and third family and of air.

Installation between two flanges ISO 7005 – PN16.

Solenoid butterfly valve series BFVS

The magnetic butterfly valves of the series BFVS are suitable to be used for control of gases belonging to the first, second and third family [not aggressive] as well as of air. On request versions for biogas are also available.

These valves, normally closed for continuous and cyclic operation, open by powering the coil and close quickly when there is no tension.

Magnetic butterfly valve are manufactured in conformity to EN 161 and to ATEX rule 94/9/CE – Zone 2 and 22 (II 3G – II 3D).

Motorized butterfly valves electronic or pneumatic actuator

Motorized butterfly valves of the series BSV and BFV are used on combustion systems as control valves. They are used in industrial field for gas or air regulation on ovens, industrial boilers and any machine equipped with the different types of burners available on the market. Motorized butterfly valves of the series BSV and BFV are suitable for all gases belonging to the first, second and third family and for air. They are DVGW-approved according to the norm EN161 and to EMC electromagnetic compatibility with CE certification.

BSV type: installation with two threaded flanges EN 10226 from Rp 3/4 to Rp 2.

BFV Type: installation between two flanges ISO 7005 PN 10/16 from DN 25 to DN 250.

Tight butterfly valve series VFW and VFL

The sealing butterfly valves of the VFW and VFL series are used in the most varied industrial sectors, both for the interception and for the regulation of ambient temperature air and of gas belonging to the first, second and third family. This series of butterfly valves offers the advantage of a particularly reduced size and weight, an elastomer seal seat with an internal metal ring which, in addition to ensuring its geometric and dimensional stability, facilitates its replacement in case of accidental breakages and other non-corrosive fluids . The VFW models are of the wafer type, while the VFL models are of the lug type, they are equipped with a yellow lever and, upon request, can be supplied complete with electric or pneumatic actuator. The VFW and VFL butterfly valves comply with the 97/23 / PED directive and the EN 161 standard.

Calibration dampers are used in ventilation and conditioning systems for circuit balancing. They are inserted inside rectangular ducts or at the entrance of fans. The casing, the blades and the pins are made of galvanized steel with bushes for housing the nylon or bronze pins. The movement of the blades can be opposed or parallel.
