Product Overview

This BSP Stainless Steel Ball Valve is a general-purpose pipeline on-off control valve with BSP British Standard Pipe thread as the core connection method and 304/316 stainless steel as the main material. The thread fully complies with British BS standards and ISO international general standards. It drives the ball to rotate 90° through the handle to quickly complete pipeline opening and closing, with reliable sealing, convenient installation and excellent corrosion resistance. It is the most widely used basic valve in small-bore pipelines of the British standard system.

Available in full sizes DN6–DN100 (1/8″–4″), it strictly complies with BS EN 13828, API 608, ISO 17292 industrial valve standards, and is widely suitable for industrial and civil pipelines in Europe, Australia, Southeast Asia Commonwealth countries, as well as import and export equipment supporting, water treatment, HVAC, chemical industry, food and beverage and other scenarios.

Key Features

1. Core BSP British Standard Pipe Thread, Full Standard Adaptability

   The product fully focuses on the core design of BSP. All threads strictly follow the British standard system, fully covering two general types:

   1. BSPP (Parallel Thread, corresponding to national standard G thread): Comply with BS EN ISO 228-1 standard, 55° tooth type cylindrical pipe thread, suitable for British standard flat connection pipelines and seals, with good installation alignment and repeatable disassembly and assembly;
      

      ---

   2. BSPT (Taper Thread, corresponding to national standard Rc/R thread): Comply with BS EN ISO 7-1 standard, 55° tooth type taper thread, the engagement forms a self-locking metal seal, anti-vibration and anti-loosening, no leakage under high pressure working conditions.

      It can be directly and seamlessly connected with global general BSP threaded pipelines, fittings and instruments without adapter adaptation, perfectly matching the installation requirements of British standard industrial systems and import and export equipment.

2. All-Stainless Steel Body, Wide Corrosion Resistance Adaptability

   All wetted parts such as valve body, ball and stem are integrally formed from food-grade 304/316/316L stainless steel, with rust and acid and alkali resistance, chloride ion corrosion resistance, no heavy metal precipitation, complying with drinking water sanitary standards. It is suitable for various working conditions such as water, steam, oil, corrosive media and sanitary media, and its service life is much longer than valves of ordinary materials.

3. Floating Ball Soft Seal Structure, Bidirectional Zero Leakage

   Adopting floating ball self-tightening sealing design, the higher the medium pressure, the tighter the seal. Equipped with standard PTFE/RPTFE/PPL wear-resistant valve seat, paired by high-precision mirror grinding, the sealing grade reaches ANSI B16.104 Class VI bidirectional zero leakage, with small opening and closing torque, smooth operation, suitable for frequent opening and closing scenarios.

4. Flexible Structure, Safe, Durable & Strong Adaptability

   1-piece/2-piece/3-piece valve body options are available to meet different installation and maintenance requirements. Standard equipped with anti-static structure and bottom-mounted T-type blow-out proof stem to eliminate potential safety hazards. The handle has 90° precise limit and lock hole to prevent misoperation, and reserves ISO 5211 standard mounting pad, which can be directly matched with electric/pneumatic actuators to realize automatic control.
