Threaded gate valves
Threaded valves are used mainly in systems where compactness and ease of maintenance are important. The UKSPAR catalog presents high-quality coupling valves for a wide range of tasks.
Catalog of threaded (coupling) valves
The UKSPAR shut-off equipment catalog is filled with a wide range of coupling valves for water supply, heating systems and technological lines. There are models to choose from with different types of shut-off element, among which the most common are wedge valves. They provide high tightness of the overlap.
Parallel and gate (knife) products are also available for working with viscous or loose media. The valves can be equipped with a handwheel or an electric drive. All products meet quality standards, designed for operating pressures up to 1.6 MPa.
How to choose a threaded latch
The choice of the correct coupling valve is determined by the technical parameters of the pipeline system:
- Diameter (DN). The most common sizes are 1/2 to 4 inches. The diameter of the valve must exactly match the diameter of the pipe.
- Working pressure. Most models are designed for PN16 (up to 16 bar), which is sufficient for most water supply and heating systems.
- Medium temperature. Brass valves can withstand temperatures up to +120°C, and stainless steel valves can withstand temperatures up to +150°C.
- Type of medium. Standard models are used for water, gas and oils, and stainless steel models are used for aggressive media.
You should also pay attention to the type of flywheel and spindle - they determine the ease of control and durability of operation.
How is it different from flanged?
The main difference between a threaded valve and a flanged valve is the method of connection to the pipeline. A coupling valve is screwed onto the pipe using an internal thread. This makes installation quick and does not require additional flanges, bolts or gaskets. This ensures compactness and space saving.
At the same time, the flange connection provides greater rigidity, therefore it is used for large diameters (from DN 50) and in high-pressure systems.
Manufacturing materials
The bodies of threaded valves are made of materials resistant to mechanical stress and corrosion. Depending on the model, the following are used:
- Brass. The most popular material for household systems. Brass products are resistant to corrosion, do not emit harmful impurities and have a long service life on hot and cold water supply lines.
- Bronze. Has increased wear resistance and can withstand higher temperatures compared to brass, making it an excellent choice for steam and heating systems.
- Stainless steel. Indispensable in the chemical, pharmaceutical and food industries, where aggressive liquids, acids or alkalis are transported, which require absolute chemical neutrality of the metal.
The internal working unit, where the movable spindle and locking wedge are located, is also made of strong, abrasion-resistant alloys.
Advantages for installation in confined spaces
The threaded connection does not require additional space for flanges and bolted connections, so the valve fits compactly into limited spaces. These can be technical cabinets, basements, wiring nodes in walls, bathroom niches.
Installation is carried out without special tools. A standard pipe wrench is enough to screw onto the thread. This also saves time on sites with frequent replacement of fittings.
Areas of application
Due to its versatility and affordability, this fitting has become a standard for small and medium-sized engineering networks. It is used in domestic water supply, individual heating, irrigation and compressed air systems. It is installed at the inlets to houses, in front of meters and on branches to plumbing.
UKSPAR produces threaded valves that are easy to install and maintain tightness for decades. Choose high-quality fittings from the manufacturer.
