NEEDLE VALVES

Hy-Pro's Barstock Needle Valves and forged valve manifolds are meticulously engineered to deliver peak performance across a wide spectrum of fluids. These valves are designed to handle pressures of up to 6000 psig (414 barg), and upon special request, they can achieve ratings as high as 15,000 psig (1035 bars). They come with a choice of PTFE or Graphoil gland packing, specially tailored for high-temperature applications. Placing the gland packing below the stem thread acts as a protective barrier, ensuring that the process remains isolated from the stem threads. By firmly tightening the upper gland body, we guarantee a perfect seal, effectively eliminating any potential leakage.
