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 Industrial Service
The Besa Series 240 Safety Valve is a spring-loaded safety valve designed to protect pressure vessels, pipelines, and process equipment from overpressure conditions in air, gas, steam, and liquid services. Manufactured in accordance with EN 4126, the Series 240 is selected where certified pressure relief performance, stable operation, and long-term mechanical reliability are required in industrial duty.
The valve is based on a semi-full or full nozzle design, with precision-machined stainless-steel internals to ensure accurate opening pressure, controlled blowdown, and repeatable reseating. Body options include cast iron, carbon steel, or stainless steel, with variants available in thermoplastic-lined execution for corrosive media. The design allows operation across a wide pressure and temperature range while maintaining compliance with PED and ATEX requirements.
Series 240 safety valves are commonly installed in chemical plants, pulp & paper mills, petrochemical facilities, utilities, and general process industries, where dependable overpressure protection and certification are mandatory. Flanged EN and ANSI connections are available, and the range covers a broad selection of sizes and pressure classes to suit standardised plant layouts.
Key Benefits for Technicians, Engineers & Production Managers
- Accurate overpressure protection — EN 4126-compliant nozzle geometry ensures predictable opening and stable discharge characteristics.
- Regulatory compliance assured — PED and ATEX certification supports use in regulated pressure equipment installations.
- Consistent reseating performance — precision-guided internals maintain tight closure after relief events.
- Material compatibility with process media — multiple body and trim options allow matching to corrosive, clean, or utility services.
- Reduced maintenance risk — robust mechanical construction limits wear under cyclic or continuous operation.
- Simplified plant integration — standard EN and ANSI flanged connections suit existing piping systems.
- Lifecycle support available locally — repair, testing, and spring-pressure calibration services support ongoing compliance.

Safe Filling. Tight Shut-Off. Long-Term Reliability.
The NAF-ProCap capping valve is specifically engineered for the demanding conditions found in batch pulp digesters, where safe, controlled chip filling and reliable shut-off are essential for maintaining production uptime. Designed as a quarter-turn ball segment valve with heavy-duty materials, the ProCap ensures dependable operation during high-load cycles, pressure fluctuations and severe chemical exposure commonly encountered in the pulp and paper industry.
Its robust construction—including a reinforced hub design, welded Alloy 21 sealing surfaces and stainless steel body—provides excellent resistance to erosion, wear and thermal cycling. The ProCap’s eccentric ball segment is machined to deliver tight sealing performance and withstand the repeated mechanical stresses of rapid open/close cycles. Optional SIL-rated safety functions and independent “jammer” lock systems further enhance digester protection.
With direct actuator mounting and availability in large sizes up to 30–32 inches, the NAF-ProCap offers a compact, reliable capping solution that integrates seamlessly into modern or legacy digester platforms. From safety-critical isolation to efficient chip charging, it provides pulp mills with a durable, low-maintenance valve package designed for long service life under harsh operating conditions.
For technicians, engineers and production managers, this means:
- Higher digester availability – Reliable shut-off performance supports stable batch cycles and reduces chip loss events.
- Improved operator safety – SIL-capable actuation, secure locking systems and robust sealing lower the risk of unplanned openings.
- Extended component life – Alloy 21 and reinforced hub/seat materials resist wear from chips, chemicals and high mechanical loading.
- Reduced maintenance interruptions – Streamlined internal design minimises build-up, improves flushing and simplifies inspection.
- Lower total cost of ownership – Durable construction and optimized sealing reduce replacement frequency and improve lifecycle performance.
- Dependable performance under harsh conditions – Engineered specifically for pulp mill digester duties, not adapted from general-purpose valves.
