Our range of hand operated stop valves have beendesigned for the fine control and shut off for high pressuregases and liquids covering sizes from 6.35mm to 38.1mm(1/4" to 1.5") orifice diameters.

For the small orifice sizes a simple screw-downunbalanced design is used. But for applications where thecombination of size and pressure would give unacceptablespindle loads a partially balanced, or fully balanced seat isemployed. Many of our stop valves are fitted with a non-rising stem, this allows for full adjustment withoutcompromising surrounding space.
