Key Features

Needle regulating valves suitable for instrumentation circuits and generally high-pressure lines up to 4' diameter.

Different connections, NPT (ANSI B2.1), BSPP (DIN 259), SW (ANSI B16.11); BW, SW OD, Flanged, Mixed.

Various materials available from Carbon Steel, 316/316L Stainless, Brass, Duplex, Superduplex, Hastelloy, Monel among others.

Rating: Different series are available depending on the pressure. The 3000 Series is up to 255 bar, and 6000 Series up to 425 bar. We also have 600 series and 10000 PSI (700 bar).

Closure and tests:

These valves are designed for high performance.
The shut-off is metal to metal, optionally available with soft seat. 100% of the valves are tested hydraulically and with helium according to API 598.
Valves are also supplied with EN 10204 3.1 certificates

Backseat

Special stem with back seating function, which allows the change of the packing with the circuit operating.
Similarly, to fully open the valve, the rear locking system prevents fluid contact with the packing, extending the life of cycle of the valve.
