Industries Served
Oil and gas valves are critical, heavy duty components designed for isolating, regulating and controlling the flow, pressure and temperature of hydrocarbons in harsh environments. Key types include ball, gate, globe and check valves, often operating under extreme pressures and temperatures. These components ensure safety in upstream, midstream and downstream operations, including LNG and pipeline transport.
Industrial chemical valves are specialised flow control devices designed to manage corrosive, hazardous or high pressure fluids in processing plants. Key types include ball, butterfly, diaphragm, gate and check valves made from corrosion resistant materials such as stainless steel, PTFE and ductile iron. They ensure safety, precise flow regulation and prevention.
Industrial mining valves are specialised, heavy duty flow control devices engineered to manage abrasive slurries, tailings and corrosive chemicals in harsh mining environments. Key types include slurry knife gate valves, rubber lined pinch valves, ball valves and check valves, which ensure reliable isolation, regulation and safety.
Power generation valves are critical components used in thermal, nuclear and renewable energy plants to regulate, isolate and control high pressure and high temperature steam, water and fuel. They ensure system safety and efficiency through turbine protection, steam isolation and pump safeguarding. Key types include globe valves for throttling, gate valves for on and off control, butterfly valves and check valves.
Steel manufacturing valves are specialised, high performance flow control devices designed to operate in the extreme environments of steel mills, including high temperatures, abrasive slurry and corrosive media. These valves are critical for controlling gases, liquids and slurries across various stages, from ironmaking and continuous casting to rolling and finishing.
Industrial pulp and paper valves are specialised, heavy duty flow control components designed to handle abrasive slurries, corrosive chemicals and high consistency pulp fibres. Key types include knife gate valves for isolating stock lines, segment ball valves for precise control and corrosion resistant valves for bleaching.
Water and wastewater valves are critical components for controlling, isolating and directing flow in treatment plants and distribution networks. Essential types include resilient seated gate valves for isolation, butterfly valves for flow regulation, check valves for backflow prevention and specialised knife gate valves or plug valves for handling sludge. These corrosion resistant and durable components are vital for safe water handling.
Ensuring consistent temperature and flow during processing.
