Main Features and Advantages

Corrosion&High-Pressure Resistance for Harsh Environments

The TRVC070999000 BOTTOM is built with stainless steel 316 or high-grade carbon steel,making it resistant to corrosive media like crude oil,seawater,and chemical solvents.A petrochemical plant in the Gulf of Mexico reported that the TRVC070999000 BOTTOM(paired with NRD108031 Viton gaskets)operated continuously for 5 years in saltwater-exposed offshore valves without signs of rust or leakage—outperforming generic carbon steel assemblies that failed every 18 months.Its high-pressure rating(up to 10,000 PSI)also makes it suitable for high-pressure applications like wellhead valves in oil drilling.

Leak-Tight Sealing with NRD108031 Compatibility

The NRD108031(typically a gasket or O-ring kit)is engineered to perfectly fit the TRVC070999000 BOTTOM,creating a reliable seal that meets strict emission standards(e.g.,ISO 15848).A water treatment plant using chlorine injection valves found that the TRVC070999000 BOTTOM/NRD108031 pair reduced chlorine leaks from 5 ppm to 0.1 ppm—well below regulatory limits and eliminating worker exposure risks.The seal’s flexibility also accommodates minor thermal expansion of the valve body,preventing leaks during temperature fluctuations.

Legacy Valve Compatibility for Cost-Effective Upgrades

Many facilities operate legacy process control valves(20+years old)that are no longer in production,but the TRVC070999000 BOTTOM is designed as a direct replacement for these systems.It fits standard actuator footprints(e.g.,Fisher DVC6200,Emerson Bettis)without requiring modifications to the valve body or actuator.A power plant in Europe saved$30,000 by replacing faulty actuator bottoms with TRVC070999000 BOTTOM(paired with NRD108031 hardware)instead of buying new valves—extending the life of their existing valve infrastructure by 10+years.

Easy Installation&Low Maintenance

The TRVC070999000 BOTTOM features pre-drilled mounting holes and clear alignment marks,allowing maintenance teams to install it in under 2 hours(vs.4+hours for custom assemblies).The NRD108031 kit includes all necessary seals and hardware,so teams don’t need to source separate parts.A refinery’s maintenance supervisor noted that the assembly’s simple design reduced valve downtime during replacements by 50%,critical for maintaining continuous production in crude oil processing.

Application Field

In oil&gas production,the TRVC070999000 BOTTOM(with NRD108031)is used in wellhead and pipeline valves.A shale oil operation in Texas uses the assembly to mount pneumatic actuators on 4-inch wellhead valves,where it withstands high pressure(8,000 PSI)and exposure to crude oil and drilling fluids.The NRD108031 Viton gasket prevents hydrocarbon leaks,ensuring compliance with EPA emission regulations and reducing the risk of environmental incidents.

In petrochemical plants,the pair secures actuators on reactor feed valves.A polyethylene plant in Asia uses the TRVC070999000 BOTTOM to mount electric actuators on valves controlling ethylene feedstock—operating at 150°C and 5,000 PSI.The assembly’s stainless steel construction resists ethylene’s corrosive effects,while the NRD108031 gasket maintains a leak-tight seal,preventing costly feedstock losses and ensuring reactor pressure stability.

In water treatment,the TRVC070999000 BOTTOM/NRD108031 pair is critical for chemical dosing valves.A municipal wastewater plant uses the assembly on valves that inject aluminum sulfate(for coagulation),where the NRD108031 NBR gasket resists chemical degradation.The assembly’s robust design has reduced valve maintenance from quarterly to annual,cutting maintenance costs by 75%.

In power generation,the pair is used in boiler feedwater valves.A coal-fired power plant in the U.S.uses the TRVC070999000 BOTTOM to mount hydraulic actuators on 6-inch feedwater valves,operating at 200°C and 6,000 PSI.The assembly’s high-temperature tolerance and leak-tight seal(via NRD108031)prevent feedwater leaks,protecting boiler efficiency and avoiding unplanned shutdowns.

Installation and Maintenance

Pre-installation preparation:Confirm the TRVC070999000 BOTTOM matches the valve size(e.g.,4-inch)and actuator torque rating(e.g.,200lb)to avoid misfit.Inspect the NRD108031 component for damage(e.g.,cracked gaskets)and verify it’s compatible with the process fluid(e.g.,Viton for chemicals,NBR for water).Power off/bleed pressure from the valve to ensure safe installation—never work on pressurized valves.Clean the valve body’s mounting surface with a wire brush to remove rust or debris,which could prevent a proper seal with the NRD108031 gasket.

Maintenance recommendations:Perform monthly visual inspections of the TRVC070999000 BOTTOM—check for fluid leaks(around the NRD108031 seal)and loose mounting bolts.Tighten bolts to the manufacturer’s torque specification(typically 50-80 ft-lbs)if loose.Every 6 months,remove the TRVC070999000 BOTTOM to inspect the NRD108031 seal—replace it if signs of wear(e.g.,hardening,cracks)are present,even if no leaks are visible.For corrosive environments,apply a thin layer of anti-corrosion grease to the assembly’s external surfaces annually to prevent rust.If the TRVC070999000 BOTTOM shows signs of deformation(e.g.,from overpressure),replace it immediately to avoid actuator failure.
