Product Formation

The Iron Hand Wheel BSP Thread PN20 Brass Gate Valve is a manual gate valve with a main body made of brass, an iron handwheel, British Standard Pipe (BSP) thread connections, and a nominal pressure rating of PN20 (20 bar). It is mainly used for controlling the on-off of fluid pipelines and is suitable for fluid systems with medium and low pressure non-corrosive media.

Product Features

The features of the Iron Hand Wheel BSP Thread PN20 Brass Gate Valve are concentrated in the collaborative optimization of material combination, structural design, performance parameters, and application adaptability. It not only retains the basic advantages of gate valves but also meets the refined needs of medium and low-pressure fluid systems through specific configurations. The features are as follows:

Brass valve body/bonnet: Made of leaded brass or ordinary brass through casting/forging, it has excellent corrosion resistance (especially in fresh water, air, and weak acid-base environments), good mechanical strength (tensile/compressive strength better than plastic, toughness better than cast iron), and easy machinability (high forming precision of complex flow channels). It is not easy to rust and scale after long-term use, and has a longer service life than cast iron gate valves.
Specialized for non-strongly corrosive media: It clearly avoids strong acids (such as hydrochloric acid), strong alkalis (such as sodium hydroxide), and high-particle fluids (such as mud), and focuses on clean/low-impurity fluids (tap water, compressed air, lubricating oil, air-conditioning chilled water). This protects the sealing surface and gate from erosion and wear, and extends the maintenance cycle.
Adaptable to bidirectional flow: Most models support forward/reverse sealing (no mandatory requirement for installation direction), simplifying pipeline layout;
Visualization of on-off status: The "fully open/fully closed" status can be directly judged by the number of handwheel rotation circles (usually 5-8 circles to complete the full stroke) or the exposed height of the valve stem (common in "rising stem design"), avoiding misoperation (such as gate vibration and wear caused by half-opening).
Simple maintenance design: Micro-leakage at the threaded connection (BSP) can be quickly repaired by wrapping raw material tape or applying sealant without disassembling the valve body;The structure is simple (no complex springs/pneumatic components). In case of failure, only the flexibility of the handwheel, the tightness of the packing, or the replacement of seals needs to be checked, resulting in low maintenance costs.
