Needle valve has performance and reliability

Instrument needle valve provides easy flow regulation in all applications, including shut off and throttling for pressure gages and instruments.  With a one piece, hot forged brass body construction, years of maintenance-free service can be expected.  The needle valve, with its tamper-proof design and blowout-proof stem, provides excellent performance and reliability. FD-LOK instrument valves are designed for positive leak tight shut-off and regulation of fluids in process, power, and instrumentation applications. The series needle valves provide the user with the utmost in flexibility when designing miniaturized tubing or piping systems.
