Outstanding BSP (British Standard Pipe) Ball Valves

BSP Ball Valves are critical in a variety of applications, especially in the water, oil, and gas industries. The type of BSP Ball Valve you utilize mostly depends on your application.

They regulate the flow of substances such as water, pressure, steam, and gases through your application. Moreso, they offer you exceptional application shutoff and control for your applications.

At Kinvalve, we offer you two main types of BSP ball valves. These include BSPP (British Standard Pipe Parallel) and BSPT (British Standard Pipe Tapered). Both BSPT and BSPT have the same shape and pitch angle.

BSP ball valves are commonly used in the United Kingdom and Commonwealth countries, including Australia.

Note that BSP threads are sometimes confused with the American NPT version pipe threads. However, they are not interchangeable. Thread pitches are different for the two in most sizes.

What is BSPT?

BSPT stands for British Standard Pipe Tapered. The thread is tapered and has an interference fit. A typical BSPT is characterized by tapered connections of the threaded portions.

For BSPT ball valves, threads are angled at 55˚, from the crest to the root. For a tight seal, thread wedging combined with Teflon tapes is used.

BSPT threads are denoted by the use of the letter “R”. Next is the size specification, for instance, a denotation for a BSPT thread of 3 inches is shown as R 3”. They are also specified by ISO 7.

Note: BSPT is sometimes mistakenly identified as NPT. However, male NPT can be fitted to a female BSPT, but due to their thread angle difference, seal effectiveness will not be achieved for fluids.

What is BSPP?

BSPP stands for British Standard Parallel Pipe. BSPP ball valves have threads that are parallel. Their thread fitting utilizes a bonded seal ring to actualize sealing.

To form a tight seal, the male thread is made longer. For BSPP utilized in port applications, a washer and an O-ring are vital to achieving an effective seal.

Like the BSPT, the BSPP threads flank angle is 55˚. BSP are denoted by the letter “G”, therefore G1” means a parallel 1-inch BSP thread.

BSPP connections are mostly used in the United Kingdom, South Africa, New Zealand, and Australia.

Sizes and Uses of BSP Ball Valves?

We have charted for you some common uses for various sizes of BSP Ball Valves.



¼ BSPMostly useful for compressed air connectors
3/8 BSPUsed in central heating for oil line connectors
½ BSPUsed for tap outlets, radiator connectors, etc.
5/8 BSPThey are used for tap outlets etc.
¾ BSPCommon use includes washing machines inlet hose connectors
1 BSPCommon uses include domestic hot water cylinders and heating boilers
1 ½Useful in central heating pumps

Kinvalve supplies the complete product line of BSP ball valves, regardless of one piece ball valves, 2 piece ball valves, 3 piece ball valves, or 3 way ball valves.

What are the Features of BSP Ball Valves?

  1. Anti-Blowout stem design- The primary design allows the stem to be installed from inside the valve body. With the stem in position, the BSP Ball valve can effectively prevent a blowout. We use O-rings and graphite rings to seal the stem. We also ensure that the stem is permanently in position by bolting the stem housing to the body.
  2. Antistatic devices – These devices are essential in preventing static sparkle in your application. During the closing and opening of the valve, there is potential for sparks with the potential to cause fire throughout your whole application. The sparks may occur from friction during operations.
  3. Fire-safe – Kinvalve BSP Ball valves are fire-safe by design. They are also tested and accredited. Buying valves that are not tested and approved is a huge risk.
  4. Live-Loading stem packing design – Our BSP Ball valves also feature a way to reduce the risk of leakage. This is achieved by the constant force on the ball valve packing between pressure and thermal cycles.
  5. Multiple stem seals – Our BSP Ball Valves provide you with multiple seals to ensure a high degree of protection against any leakage.
  6. Optional packing- Packing is vital in preventing leakages. We can provide you with effective and high-quality packing for your application.
  7. Body gasket materials – We provide you with highly effective gaskets. We use either graphite or PTFE (Polytetrafluoroethylene).

Our BSP Ball valves are made from high-quality rust-proof 316 stainless steel. The 304 stainless steel is also utilized.

The Ball is made from 316 stainless steel, while the gland nut, washers, and PTFE stem packing and seals are made of 304 stainless steel. This guarantees permanence for your BSP ball valve.
