Packless valves
Packless valves, such as those from HOKE’s 0300, 4100, 4200, and 4600 series, utilize welded bellows or diaphragms instead of traditional stem packing. This design ensures zero-leak integrity, low internal volume, and exceptional chemical resistance; making them ideal for critical applications like gas sampling, high-purity systems, or corrosive media. Operational ranges span from deep vacuum to pressures up to 2,000 psig and temperatures from cryogenic (–320 °F) to high-heat (up to +1,200 °F) conditions, depending on the series.
