Valves are an important member of the water and wastewater industry and similar industries due to the disconnection and connection of liquid flow in open canals. Basically, the valves are used to control the flow of fluids such as water and sewage entering the treatment plants and pumping stations. The function of these valves is usually to control the height of the fluid, the velocity of the fluid or the blockage of the channel to change the direction of fluid flow and in some installations such as garbage collectors and pumping stations in emergencies to repair or remove from the operating circuit. are being used . Valves, depending on their application, have three sealing sides and four sealing sides.
Main parts of valves:
- frame
- Gate
- Spindle assembly (including screw shaft, brass nut, handwheel and handwheel support)
- Gearbox (if required)
- Electric actuator (if required)
Types of valves based on design:
- Valves attached to the wall / valves inside the channel
- Uniaxial valves / Biaxial valves
- Movable valves (ascending) / non-movable
- Manual / electric valves
- Valves on three sides of the seal / four sides of the seal
Materials used:
- AISI 316 or AISI 304
- ST-37 (with paint or hot dip galvanizing)
