Bifold has built on the experience and skills of its workforce to continually broaden its product
range. In addition to the high quality valves and pumps, Bifold are proud to announce the launch of
their solenoid operated BXS Pneumatic valve range.
Bifold’s BXS valve range offers a compact and flexible solution to low pressure applications. With
over 35 common interface modular operators, this versatile range covers a wide spectrum of
actuation requirements. Specifically, the solenoid operated types are compact, two-stage valves.
The robust design is manufactured from 316L stainless steel as standard with anodised aluminium
options also available. The valves are suited for offshore and other corrosive atmospheres.
With a valve operating temperature range of -55°C to + 130°C and worldwide solenoid operator
approvals Ex emb, Ex d & Ex ia for ambient temperatures up to 90°C, the solenoid operated product range is available with the widest range of override options. These include: auto reset, spring return manual override, stayput manual override, manual reset, tamperproof manual latch and latch
energised. Low power options are also available, rated at only 1.8W.
Product design FMEAs, extensive qualification testing, computerised diagnostic factory acceptance
testing and test procedures to confirm operational safety factors of all production valves, combine to
support the certification of the BXS series valves as SIL 3 capable.
A NAMUR interface is available on 5/2 port configuration valves. These types are supplied with
multi-functional adaptor plates to permit valve orientation through 90° or conversion to a 3/2
configuration.
Alongside the development of the BXS series valves, Bifold has designed the IPV (Integrated Pilot
Valve). This is a cartridge valve that fits within the solenoid operator adaptor, permitting the
solenoid operator to be connected directly to the
BXS series valve body. This will be a more
compact, simpler to maintain and more cost effective solution for the end user.
