Hand Valves

Pneu-Hydro hand valves offer design and operating features not typically found on valves of this pressure range. The Teflon stem packing is located below the stem threads and pintle swivel. This helps prevent contamination and lubrication washout by isolating this critical area from the process fluid. This, combined with the very low operating torque (less than 10 lb-inches), provides a precise “feel” and adjustment sensitivity over the lifetime of the valve.

The valve stem is designed so that it cannot be inadvertently backed out of the valve. The low profile makes this valve ideally suited for panel mounted or other limited space applications.

Standard features include self-aligning swivel pintles to minimize seat scoring, Teflon stem seal, and 316 stainless steel construction to provide maximum compatibility with corrosive fluids.
