The extended Hoke series of analytical instrumentation includes new selector valves, miniature metering valves and low dead volume fittings, all offering the versatility to combine with existing products and provide system solutions for wide-ranging user needs.
New 5-way and 7-way Selector Valves have a simple low-maintenance low dead volume design and bi-directional flow with individual port shut-off. In 316 stainless steel with Viton O-rings as standard, they are available in a wide range of special materials and sealing elements, have a Cv rating of 0.10 and an operating temperature range of -40°C to +120°C.
The Hoke Miniature Metering Valves give fine control within a compact design featuring micrometer vernier handle, external locking stem sleeve, panel mounting and 1/16in Gyrolok end connections. For pressures from vacuum to 6000 psig and temperatures of -55°C to +230°C, they come in 316 SS with Dyna-Pak Teflon packing or O-ring seals.
LDV Low Dead Volume Fittings in 1/16in and 1/8in sizes combine leak-tight operation with the ability to be repeatedly remade. Providing the same high reliability connections as the proven Hoke Gyrolok tube fittings range, they are also supplied in 316 SS as standard or other materials to order.
Other Hoke analyser items include ball valves with 'unique' shut-off and diverting capabilities, needle valves for sampling as well as analytical systems and Gyrolok tube fittings now available with 'Safety Changers' for safe and effective component replacement.
