Read WDL Valve guides on industrial valve selection, materials, standards and applications for oil, gas, chemical, power, water and severe service.
Low Emission Valve Selection begins with the fluid, pressure, temperature, operating cycles and required emissions test standard. For hydrogen, natural gas and CCUS service, select the complete valve assembly by checking the body joints, stem or shaft seal, gasket, surface finish, bolting, actuator loads and production test records. Why this topic matters in 2026: hydrogen…
A pneumatic high performance triple offset wafer butterfly valve combines non-rubbing triple-offset geometry, a multilayer metal sealing system and pneumatic quarter-turn operation. It is designed for automated shutoff in high-temperature, high-pressure and high-cycle industrial pipelines where conventional soft-seated butterfly valves may not be suitable. How Does a Triple Offset Butterfly Valve Work? The first offset…
A high performance double offset wafer butterfly valve is a compact quarter-turn valve designed for reliable isolation and frequent operation. Its offset disc-and-stem geometry helps the disc move away from the seat early during opening, reducing rubbing, seat wear and operating torque compared with a conventional concentric butterfly valve. How Does the Double Offset Design…
The WDL Duplex Ball Valve provides fast quarter-turn isolation, a direct flow path and dependable shutoff for seawater, desalination, offshore and chloride-containing process systems. WDL can manufacture the valve in Duplex 2205, Super Duplex 2507 or another project-specified duplex grade. WDL Duplex Ball Valve with project-selected duplex material, connection, seat and operating method. What Is…
A side entry cryogenic ball valve for LNG service uses a two-piece or three-piece body, low-temperature materials and an extended stem to provide reliable quarter-turn isolation at temperatures down to −196°C. Correct seat design, body-cavity relief and cryogenic testing are essential because trapped LNG expands rapidly when it warms. WDL Side Entry Cryogenic Ball Valve…
A top entry cryogenic ball valve provides quarter-turn isolation for LNG, liquid nitrogen and other low-temperature media. Its top-access body allows internal components to be inspected from above, while an extended stem keeps the packing and operator away from the cold pipeline and surrounding frost. WDL Top Entry Cryogenic Ball Valve for project-specific low-temperature isolation…
A NAB C95800 globe stop-check valve combines manual shutoff and flow regulation with automatic protection against reverse flow. Its nickel aluminum bronze body makes it suitable for selected seawater, marine cooling-water and shipboard utility systems. WDL NAB C95800 globe valve. Stop-check configurations can be manufactured according to the project specification. What Is a NAB C95800…
Petrochemical process valves isolate equipment, regulate flow, prevent reverse flow and provide emergency shutoff in refining and chemical production units. The correct valve must match the medium, pressure, temperature, corrosion risk, emissions requirement and operating frequency. WDL Valve supplies ball, gate, globe, check, butterfly, plug and control valves for hydrocarbons, gases, steam, acids, solvents and…
Offshore oil and gas valves provide isolation, pressure control and backflow protection on platforms, process modules and marine utility systems. Valve selection must account for operating pressure, hydrocarbons, chlorides, hydrogen sulfide, external saltwater exposure and limited maintenance access. WDL Valve supplies ball, gate, globe, check and control valves for hydrocarbon, produced-water, seawater, gas and utility…
Pulp and paper valves isolate equipment, control flow and prevent reverse flow in stock preparation, chemical recovery, bleaching, steam, water and wastewater systems. The correct valve must resist corrosion, fiber accumulation, scaling and abrasive solids without restricting the process. WDL Valve supplies ball, butterfly, gate, globe and check valves with metallic or soft-seated configurations for…
