Accurate digital valve position feedback with advanced diagnostics for hazardous-area automation.
The Digital EPIC D200 transmitter provides precise 4–20 mA position feedback with HART® 7 communication, improved linearity and reduced hysteresis in a compact, explosion-proof or intrinsically safe enclosure. A clear LCD screen, push-button auto-calibration and a standard non-contact position sensor simplify commissioning and support reliable long-term operation. With options for hermetically sealed Magnum switches, NAMUR sensors and integral Falcon V solenoid valves, the D200 delivers a versatile platform for monitoring and control across a wide range of rotary and linear valves.
For technicians and engineers, this means faster calibration, improved diagnostics and higher position accuracy.
Intrinsic safety, reliable valve position monitoring and long-term durability for demanding industrial environments.
The AccuTrak 3300 rotary position monitor provides accurate valve position feedback in a compact unit certified for intrinsically safe (ATEX/IECEx) applications. With a 360° Beacon™ visual indicator, hermetically sealed Magnum switches, and inductive NAMUR sensors, the AccuTrak series delivers dependable feedback even in corrosive or hazardous areas. Pre-wired terminals, additional conduit entries and standardised mounting patterns simplify installation and wiring. Resin, aluminium or stainless-steel housings offer strong protection against chemicals, moisture and mechanical impact.
For technicians and engineers, this means safer operation, faster setup and reduced maintenance in all rotary valve applications.
Reliable Overpressure Protection for API 526 Duty
The Besa 290 API safety valve is a spring-loaded pressure relief valve designed to protect pressurised equipment against overpressure in steam, gas and liquid services. It is built in accordance with API 526 and uses an adjusting ring to tune opening and reseat behaviour, which is important where stable lift, repeatable blowdown and controlled closing are required across changing process conditions.
For typical plant duties, the Besa 290 is supplied in flanged patterns with high-flow, full-nozzle construction and a defined performance basis aligned to API sizing practice (API RP 520 basis is referenced in the 290 technical bulletin flow-rate notes). The published operating characteristics for the 290 series include effective discharge coefficients (Kd) for gas/vapour and liquid service and standard overpressure and blowdown expectations used during sizing and selection.
For technicians, engineers and production managers, this means:
- Fewer nuisance lifts — the adjusting ring allows set-up of stable popping and closing behaviour for consistent relief performance.
- More predictable capacity sizing — published Kd values support repeatable engineering calculations for gas/vapour and liquid duty.
- Clear protection margins — defined overpressure basis (gas/vapour vs liquid) supports compliance with typical relief design assumptions.
- Controlled return to service — defined blowdown expectations help avoid extended loss of product or unstable reseating after a lift event.
- Simpler plant standardisation — one API-pattern valve family covers steam, gases and liquids, reducing spares variety across units.
- Improved maintainability planning — optional accessories such as test gag and limit switch support functional checks and lift indication where required.
- Material fit for duty — availability of carbon steel and stainless steel constructions supports common refinery, chemical and utility services.
