Multiplex Engineering was established in 1989 and celebrates its 25th year of supply and service in the valve and instrumentation sector. It employs 30 staff from its modern well equipped premises in Chesterfield.
Multiplex Engineering are the official GE Masoneilan control valve sales and repair centre for Scotland and England Central. They stock Masoneilan products and spares and have GE factory trained and approved technicians .Control valves and positioners are available for same day delivery. Multiplex’s repair staff are familiar with all types and manufacture of valves including pressure relief valves.
Multiplex have a valve repair facility approved and audited by GE Masoneilan and offer quality service and repairs to any valve.
A comprehensive range of quarter turn scotch yolk actuators from Bettis and Flowbus are stocked to enable very fast delivery of ESDV and actuated ball valves complimented by a large inventory of Trunnion mounted ball valves.
Multiplex are official Foxboro stockists and carry a large inventory of pressure transmitters and valve positioners for immediate delivery – most products from the Eckardt range of valve positioners are stocked including ATEX certified.
Multiplex also carry a stock of Bifold and Maxseal solenoids valves as well as Westlock valve switchboxes. Multiplex has its own engineering dept and can manufacture mounting kits for actuators and ancillaries.
Multiplex have a team of technicians and mechanics in both control valve and instrumentation departments some of whom are certified BOSIET and MIST for work on offshore installations and all are available to perform service / repair work to valves and instrumentation at our workshops or onsite at any location .
Multiplex have a dedicated panel fabrication dept and can fabricate hydraulic , pneumatic and electrical panels.
