2-Way ball valve of brass from JP Fluid Control with G1 inch pipe threads (BSPP) and a full bore (25 mm). The 100-4MS series is designed for use in drinking water applications and has a anti legionella design. An extra hole in the ball connects the entrapped space around the ball. This significantly reduces the risk of the growth of bacteria due to stagnant water. The valve has a pvc coated lever for manual control. The ball valves in the 100-4MS-series of JP Fluid Control are characterized by long life.

The valve has female thread on both sides (1 inch). This is BSPP (British Standard Pipe Parallel). With our range of 1" fittings, the valve can be installed in any pipe (recommended pipe diameter ± 20 - 30 mm).


This ball valve can be manually operated by a lever. By rotating 90 degrees, the valve is open or closed. If the lever is perpendicular to the pipe, the valve is closed. This valve is not suitable for electrical or pneumatical control. For this purpose, valves with ISO-Top flange (ISO 5211) are recommended.


This ball valve is part of the 100-4MS series and is designed for drinking water applications. The valve design prevents the stagnation of water in the hollow spaces around the ball. As a result, the risk of growth of bacteria such as Legionella is greatly reduced. Moreover, the construction reduces the risk of frost damage during winter. The housing of the valve is made of brass, the ball is made of hard chromed brass and the seals are made of PTFE. The valve is suitable for various media, such as water, oil or air up to a maximum of 25 bar. For corrosive or aggressive media, a valve made of plastic or stainless steel is better suited. The valve can be used up to a max pressure of 25 bar and a temperature between -10 and 90 °C.
