Brass ball valve 4MS 15S female female BSP red handle 3/4'' - Pack of 10

The 15S series brass ball valve is designed for controlling water flow in plumbing installations, particularly those intended for drinking water . It is ACS (Attestation de Conformité Sanitaire) certified, which guarantees that it complies with French sanitary standards for use with water intended for human consumption.

This valve has a semi-integral bore , which means that the inner diameter of the valve is slightly smaller than that of the pipe. This provides a good compromise between fluid flow and reduced pressure losses, while maintaining a compact structure. The wide flat seat ensures a better contact surface between the internal elements, which improves the sealing and reliability of the system.

Sealing is ensured by a PTFE (polytetrafluoroethylene, also known under the brand name Teflon) gland , a material highly resistant to heat, chemicals, and friction. This guarantees a long-lasting, maintenance-free seal , even in demanding environments. The anti-ejection shaft enhances safety: it is designed so that it cannot be ejected from the valve under pressure, thus reducing the risk of leakage or malfunction.

The reversible handle allows for flexible installation, as it can be easily repositioned depending on the mounting orientation. It is also treated against corrosion , which extends the life of the valve, especially in humid or aggressive environments. From the DN1" (1 inch) diameter, the valve is equipped with a stainless steel ball , which offers increased resistance to wear and corrosion and ensures smooth and long-lasting operation.

In summary, this valve is ideal for plumbing systems requiring high reliability, long service life and compatibility with drinking water . It is particularly suitable for domestic, commercial or industrial installations where safety and performance are essential.
