BRAND: NAFCATEGORY: Ball Valves

The NAF-Triball is a high quality cost effective 3 piece ball with optional soft or metal seats having a wide range of end connections. It is ideal for isolation and on/off as well as control when fitted with the metal-seated solution with seat rings in Alloy 6. Options are available for sample valves where the ball needs to be close to the main pipe, to eliminate plugging. This solution can also be successfully used in pipe connections with high vibrations. The 3 piece body makes stripping the valve simple.

The floating ball design means the valve is tight in both directions even at low differential pressures and the packing gland can be tightened if required. It is available with an ISO top for easy mounting of pneumatic actuators. The NAF Triball is equipped with lockable hand lever as standard. It can operate up to a maximum of 40 bar, and is CE-Marked according to Pressure Equipment Directive (PED  97/23/EG) module H, category III.
