The Double Lin LL5019 Brass Foot Valve is engineered for durability, precision, and long-lasting performance in water pumping systems. Constructed from HPb 57-3 forged brass, each component — including the valve body, bonnet, and spool — is produced using high-precision CNC machines to ensure zero air holes, zero blistering, and excellent sealing.
Equipped with a stainless-steel spring, NBR gasket, and stainless-steel strainer, this foot valve provides stable performance under a wide range of conditions. With a working pressure of 16 Bar (232 psi) and a temperature range from -10°C to +120°C, it is suitable for a variety of residential, commercial, and industrial applications.
The ISO228 threading (equivalent to DIN 259 and BS2779) ensures compatibility with international plumbing standards, making installation quick and reliable.
