An ATEX-approved proportional pressure controller for high-pressure, hazardous applications has been launched recently to the market by IMI Precision Engineering. The D386 proportional reducer is suitable for pressure control in a variety of nuclear and gas supply applications, from reactor vessel hydraulic control and fast shutdown systems to gas collection and monitoring, and is also suitable for new hydrogen filling stations for vehicles. A three-way regulator with a 24 VDC /2A integrated outlet pressure sensor, the D386 reducer is available with an input and output of either 0-10V or 4-20mA. Along with many of the IMI Precision Engineering range, the D386 valve is ATEX-approved, classified according to group II, category 2 G and temperature class T4 or T3 of ATEX directive 94/9/CE.
Comprising of a brass housing with a stainless steel valve and polyether ether ketone (PEEK) valve seat, the D386 reducer features a ¼” BSPP threaded port and can operate across a temperature range of -20°C to +50°C. Additionally, it offers hysteresis and reliability of < 1% of the maximum outlet pressure range for enhanced safety and control. The controller can be configured to cope with outlet pressures of up to 400 Bar with a maximum inlet pressure of 420 Bar.
