RS PRO Brass Threaded Full Port Ball Valve BSP Female 1/2 to 4 in, 3 bar, Steel Handle 812-5144

RS PRO 812-5144 is a brass full port ball valve featuring BSP female threaded inlet and outlet ports sized between 1/2 and 4 inches. Designed for industrial use, it supports a maximum operating pressure of 3 bar and operates reliably across temperatures ranging from -40°C to 170°C. The valve is constructed with dezincification-resistant ADZ-T and ADZ-P brass, providing excellent corrosion resistance comparable to bronze, making it suitable for water and fluid control systems where dezincification may be an issue.

The full port design ensures minimal flow restriction, maximizing pipeline efficiency. The valve incorporates a dual sealing system with pure PTFE self-lubricating seats that provide maintenance-free operation and prevent metal-to-metal contact for increased longevity. The chrome-plated DZR brass ball delivers enhanced wear resistance and durability, while the stem is maintenance-free due to two FPM O-rings ensuring safety and leak prevention.

The lever handle is made of Geomet® carbon steel with a thick PVC dip coating offering thermal and electrical protection. It features a lever stop to avoid undue stresses, with clear ball position indication for ease of operation. This valve complies with multiple international standards including RoHS (EU), GOST-R, PED 2014/68/UE, and EAC, reflecting its robust design and quality assurance.

Applications of the RS PRO 812-5144 Ball Valve include controlling the flow and pressure in water, oil, gas pipelines, and other industrial liquid systems. Its dezincification-resistant brass construction makes it suitable for challenging environments prone to corrosion. The hot forged sand blasted body is sealed using Loctite® or equivalent thread sealants for secure installation.

Manufactured in Italy, this valve offers reliable performance and meets demanding industry standards, trusted by engineers across various sectors including industrial, water treatment, oil and gas, and HVAC.
