A needle valve for high-pressure applications

| By Mary Page Bailey and Gerald Ondrey

This company’s new high-pressure needle valve (HPNV; photo) is designed for four pressure ranges of up to 15,000, 20,000, 30,000 and 60,000 psi. The sensitive components (spindle tip and sealing) are made of suitably resistant materials. Furthermore, the HPNV has the same characteristics as the company’s other needle valves: low-wear operation due to the non-rotating spindle tip, smooth handling with low torque and leak tightness tested to BS6755/ISO 5208 leakage rate A. — Wika Alexander Wiegand SE & Co.
