Superior quality and design is a lofty claim, but Noshok can make it with confidence. Expecting excellence in valves from a company that has designed and produced precision measurement instrumentation for the last 30 years should take no stretch of your imagination. Since 1967, when Noshok was one of very few American companies able to offer liquid-filled pressure gauges, they have stood behind their innovative products with extended warranties, setting the standard for the competition.
Today Noshok produces needle and manifold valves in a variety of sizes, designs, configurations, and purposes, including--but not limited to--mini valves, multiport valves (both hard and soft seat), 2-way hard seat needle valves, 2-way soft seat needle valves, multiport gauge valves, and block & bleed valves. But, of all the fine products manufactured by Noshok, the needle valve is probably the most revered, and the work horse of the lot. Needle valves are perfect for exacting, minute adjustments in flow control. No other valve design offers an equivalent of fine tuning only a needle valve can provide. You only need to review the details of a few examples to appreciate the level of performance Noshok delivers.
