Pressure Reducing Valve Exporters

Accurately determine :
Reduced pressure
Intel pressure
Alloeable change in reduced pressure, from maximum to minimum flow, psi
Maximum required flow.
Subtract the reduced pressure from the inlet pressure.

VALVE FUNCTION :
Inlet pressure acts upward on small balancing diaphragm (or piston in 2 ½ - 3” sizes) to equalize downward pressure on valve disc, providing fully balanced action. Inlet pressure variations are equalized without affecting set - point. When the adjusting spring is compressed, it opens the main valve to admit fluid to downstream side.

When the downstream pressure under the large diaphragm equals the force exerted by the adjusting spring, equilibrium is restored and the main valve maintains flow of the set downstream pressure.

Simply designed, your Nu-tech Hi-Flo is slated for a long, trouble-free life. Standard renewable parts never need special fitting or machining. Here’s a rugged regulator built to absorb hydraulic system shocks that upset ordinary valves.

Single Seated : Closing with inlet pressure for positive, dead-end, shut-off.

Accuracy of Regulation: Comparable to instrument control with full flow for equivalent pipe size.

New type piston with Teflon + Seal: for temperatures up to 5000 F. give continuous wiping action keeping liner clean, improving operating reliability and reducing maintenance. Piston rings can be furnished for temperatures over 5000 F.

Fully Guided Main Valve: Prevents rubbing or binding of internal parts.

Gradual Opening Ported Main Valve: in sizes 2 ½”and larger for improved throttling control under low flow conditions.

Sensitive Stainless Steel Diaphragm: responds instantly to any flow change and eliminates stuffing boxes and bellows seals. Full travel less than its own thickness stress to a minimum.

Renewable, Interchangeable Parts: machined to close tolerance; complete overhaul without machining or removing valve body from the line.
