Stainless Steel Ball Valves offers Schwer Fittings in reliable and proven quality. The many different types cover a wide range of applications in terms of functionality, pressure, temperature and media.
Ball Valves
Ball valves have proven their worth in many applications as very reliable and compact shut-off valves. Various types such as 2-way, 3-and 4-way ball valves in conjunction with various spherical bore sizes can be combined depending on the application and use. Ball valves provide fast and precise switching due to their simple structure.
Ball valves with actuator offer a clean and cost effective solution especially for automation (electric or pneumatic) by direct mounting on DIN / ISO 5211- flange.
The ball valves of Schwer fittings are available with various connectivity options like female thread according to DIN / ISO 228 or with bilateral Welding end DIN 3239, as well as 2 -or- 3-piece housing.
Non Return Valves
Return valves are offered with various unions and a variety of valve springs for different opening pressures.
Needle Valves
In addition to the non-return valves, needle valves with female threaded connections to DIN ISO 228 from G 1/8" to G 2" and with cutting ring connections to EN ISO 8434-1 are available for the light series 6L to 28L and heavy series 6S to 25S pipe dimensions
Depending on size, temperature and medium, the valves can be used for pressures up to 400 bar. Due to their simple and complex design, the needle valves are equipped with a rotatable, metallic valve cone and are suitable both as a flow control valve and for shut-off purposes
PTFE sealing packings are used to ensure a secure seal to the outside. In the standard version, the spindle adjustment thread protrudes into the media-carrying space. For applications in which very aggressive or crystallizing media are used, we recommend our "ASP" series in which the spindle adjustment thread is located outside the media-carrying area. This minimizes the risk of seizing of the spindle thread. Here too, the material and dimensions are coordinated in such a way that both the standard version and the "ASP" valve cartridge are compatible in the same valve body.
A 100% functional check for leaks before leaving the factory guarantees the highest level of customer satisfaction.
