Hoke - Gyrolok XP

GYROLOK® XP has been developed as a critical service, durable design to improve safety at higher pressures and provide easier installation on small bore tubing systems.

GYROLOK® XP incorporates design and material technology innovations that allow the fitting to be assembled onto high yield strength and thicker wall tube, compared to conventional compression tube fitting designs.

GYROLOK® XP has been fully validated across a broad range of austenitic and high-performance alloys, tubing sizes, and wall thicknesses. Examples include: 316, 6MO, Super Duplex, 625/825, HC

Unique design innovations allow the fitting to be used at higher pressures on thicker walled tubing; in some cases, eliminating the need for less reliable cone and threaded arrangements or more costly welded installation or other permanent methods.

HOKE - 7100 Series, Ball Valve Instrumentation

Used for quick on-off service with a visual indication of flow, HOKE’s 2-way ball valves offer orifice sizes up to 0.25” (6.4mm). 7100 series valves feature a floating ball design, encapsulated replaceable seats and check seals to ensure leak-tight service and extended service life.

HOKE - General Purpose Multimite 79, Ball Valve Instrumentation

Multimite 4-way, or dual switching valves allow two distinct flow paths to be used at the same time. The 5-way, or diverter valves off er the same functionality as 3-way valves except with four alternate paths.
