Process Exchange + Product Knowledge + Valve Types + Metallurgy = Our Experience

Breadth and depth of knowledge come from experience when selecting the right valve for your process applications. For over three decades TRIFLOW CORP has partnered with end users, EPCs, OEMs and licensors to exchange, challenge, and research the best solutions to ultimately improve operational efficiency and minimize downtime.

Some of our applications in the expanding world of Gases include…

Robust, hydraulically actuated large bore isolation ball valves exposed to high temperatures and pressures for feeding solid fuel into a pressurized reactor for gasification. Valves can cycle in this process every 15 to 25 minutes and are expected to handle 75,000 to 100,000 cycles.

Ball, butterfly (BFV) and gate valves constructed of stainless steel and selected for their specific flow rate, pressure and module space constraints. Oxygen cleaned. Equipped with mechanical keyed interlock system to prevent accidental opening or closing of valves under mandatory sequence conditions. Installed at a computer chip factory.

Automated, top entry, extended stem rotary valves designed to withstand extremely low temperatures associated with cryogenic hydrogen. While installed in a cold box the internals are cleverly removed for inspection and/or maintenance without compromising the cold box.

Automated rotary valves for high pressures and temperatures up to 460° C in oxygen service in ASME 600, 900 and 1500 Class, with very specific third-party tested materials of construction, and an O2 proven robust metal-to-metal seating system up to 24 inch valves.

Above and below ground natural gas isolation valves designed to meet specific operational requirements, local regulations and environmental conditions that incorporate emergency shut-off mechanically and visual indicators to enhance safety and operational reliability. Sizes range from 2 through 30 inch with extensions.

Automated and manual rotary isolation valves from 2 inch up to 48 inches with metal-to-metal seating or soft seating configurations designed for LNG service. Manufactured from materials that can withstand cryogenic temperatures and equipped with electric, pneumatic or hydraulic actuators.

Automated floating ball or triple offset valve (TOV) for emergency shutdown (ESD) applications where reliability is critical. Metal-seated floating ball valves or TOV with quick-acting actuators designed with fail-safe features and often integrated with safety instrumented systems (SIS) and process control systems.

Manual or automated floating ball or triple offset valve (TOV) with electric, pneumatic, or hydraulic actuators for remote operation and integration into control systems with emergency shut-off capabilities to: control the flow of gas through the drying media; switch between drying and regeneration cycles; and to isolate equipment for maintenance or in case of emergencies

Crossover valve designs used in pressure relief systems; for rerouting of fluids in pipeline networks; to help manage the flow of gases and liquids in processing facilities; and to isolate sections during emergency shutdowns. Can be equipped with keyed interlocks.

Knife gate valves (KGVs) to isolate and control the flow of polyethylene and polypropylene to process vessels during licensor batch processing
