For existing and new applications, it is necessary to identify the thread type to guarantee a proper connection of the joint.The BSP, or Whitworth thread, is a family of thread standards that has been adopted internationally, except in the United States.

In the Imperial “inch” system, threads are commonly referred to by measuring an […]



Metric Threads come in different pitch sizes for a given diameter: coarse pitch and fine pitches.







There are two types of BSP threads:Figure 1: A BSPP male parallel thread profile (left) and a BSPT taperd male thread profile (right)BSP threads are identified with letters each of which represents the type of thread and their associated standardsThe actual sizes of the most commonly used BSP threads are listed in Table 1 and Table 2 for BSPP and BSPT threads respectively. Indirect operated solenoid valves need a pressure differential over the inlet and outlet port for This misalignment might result in the threads to be fastened only partially.

as a Threads produced to ASME B1.13M standard are fully interchangeable with threads that are based on ISO 68-1 basic profile and ISO 965-1 tolerance practices. To ensure compatibility and ease of maintenance, threads are standardized.

Choose the right circuit function. Acceptability criteria are described in ANSI/ASME B1.3M-1992 (R2001).


choose the material for the valve body and seals. The type of medium defines the material choice of the valve body and seals. (semi-)direct operated solenoid valves can be used.







If the pressure differential is too low (f.e. The thread abbreviation includes the thread code letter and the nominal thread diameter or the thread size.
