The UKSPAR catalog presents a wide range of flanged ball valves of various types, materials and diameters that meet modern quality standards.
Flanged ball valves catalog
The Ukrainian brand UKSPAR presents a wide range of locking devices to solve problems of any complexity. In the catalog:
- steel valves with a 304 stainless steel ball and PTFE or PPL seal (PN25 and PN40);
- completely stainless steel valves with 304 stainless steel ball and PTFE seal;
- models (PN16) with a three-piece design that allows you to dismantle the internal part of the valve without disassembling the flange connections to the pipeline.
Buyers have the opportunity to choose the optimal model based on the specifics of their engineering facility.
How to choose a flanged ball valve for your tasks
To choose the right equipment, it is necessary to analyze the key parameters of the system:
- Nominal diameter (DN). The size of the passage cross-section of the fitting must exactly match the diameter of the main pipe.
- Working environment. Before purchasing, it is important to consider what substance is being transported: water, gas, steam or aggressive chemical compounds.
- Working pressure and temperature. The fittings must have a safety margin that exceeds the maximum performance of the system during peak operating times.
For domestic water supply systems, compact brass models are suitable. Industrial mains require reinforced solutions made of stainless or carbon steel.
Construction and materials
The reliability of the fittings is established at the stage of designing internal components and selecting raw materials.
Ball, stem, seal
The main working element is a ball with a through hole. It rotates around its axis with the help of a stem. To ensure absolute tightness in the closed state, PTFE seats and seals are used. This material is resistant to friction, does not deform under pressure and is chemically inert. The stem is protected against falling out under internal pressure.
Steel, stainless steel, brass
Large diameter housings are made of carbon steel - it is durable and can withstand high mechanical loads.
Stainless steel is indispensable in the food, pharmaceutical and chemical industries, is chemically neutral, does not corrode and works with superheated steam.
Brass in flanged design is rare, usually it is typical for small diameter coupling products.
Equipment: manual, with gearbox, with drive
The way the valve is controlled depends on its size and frequency of use:
- Manual (lever). Standard option for small diameters, where the operator can shut off the flow manually using a convenient lever handle.
- With gearbox. Installed on large pipe diameters. The mechanical gearbox reduces the effort required to turn the ball, making the control process easy and smooth.
- With drive. Models with electric or pneumatic drive are integrated into automated systems to control the locking unit remotely.
The UKSPAR catalog assortment allows you to choose the optimal solution for both standard pipelines and industrial systems.
Advantages of flange connection for large diameters
The flange connection withstands higher mechanical loads and higher operating pressure compared to threaded or coupling connections. The detachable design allows the valve to be dismantled for inspection or replacement without cutting the pipeline. This is important on industrial pipelines, where replacing fittings without stopping and disassembling the pipeline section saves maintenance time.
Where are they used?
The scope of operation of flanged ball valves covers industry, housing and communal services, and the energy sector. They are installed on water supply mains, in boiler rooms, on natural gas distribution lines, as well as in the oil refining industry.
The flanged ball valve from UKSPAR is the choice of engineers who need durability and safety at critical facilities.
