Low Flow Screwed Liquid Turbine Flow Meter

The FSSCDA rupture disc features precision micro-scored petals with four, six, or more radial scores, ensuring fast, controlled opening while minimising the risk of petal separation. This design makes the disc particularly suitable for high burst pressure applications. It can be used with both gases and liquids, including under cycling and pulsating conditions, without reducing safety margins. In an overpressure event, the disc activates within milliseconds and opens cleanly without fragmentation, making it ideal for protecting safety relief valves.

The FSSCDA supports an operating-to-burst pressure ratio of up to 85% and offers excellent corrosion resistance, which can be further enhanced with an optional PTFE lining. In many applications, the disc can also operate under full vacuum conditions without the need for support, providing added flexibility. These discs comply fully with ASME Section VIII, Division 1 requirements.

Six-Port, SilcoNert® 2000, Single Stage Cylinder Regulator for Reactive Analytical Applications

The CONCOA 420 Series regulator, treated with SilcoNert® 2000, is designed for primary pressure control of reactive or corrosive calibration mixtures and pure gases, providing an extremely inert wetted surface. The proprietary amorphous Silicon CVD coating delivers superior inertness and corrosion resistance compared to bare 316L stainless steel or other alloys. In its six-port configuration, the 420 Series is suitable for applications tolerating minor outlet pressure fluctuations or with gases stored below 500 PSIG (35 BAR). Maximum inlet pressure is at least 3000 PSIG (210 BAR), with optional configurations up to 4500 PSIG (310 BAR). Factory-installed options include single station manifold setup, purge, low-pressure alarm, or multiple inlets.

The Brownall Air Eliminator is essential for any heating system to effectively eliminate air pockets. This reliable valve can withstand a maximum pressure of 10 bar and operates efficiently at temperatures of up to 93°C. Formerly marketed as the Charles Winn Automatic Air Eliminator, more than 200,000 units have been sold across the UK over the past 25 years. Many of these valves remain in service today, demonstrating their exceptional durability and ability to provide long-term, trouble-free operation.
