Series 2HX/2HDX/2HBX & 3HX/3HDX/3HBX Design Improvements Increase Reliability

Class 1 service polyurethane rod wiper, seal and o-rings (rod gland static seal and body end seals) offer superior abrasion and extrusion resistance for longer service life.

High compressive strength non-metallic piston wear rings, that minimize tube scoring, are standard on all configured piston selections.

One common piston is used for 4 piston seal styles. When changing operating conditions require a different seal style, the piston and rod assembly is unchanged.

Cartridge style needle valve with captive micro adjust screw for precision cushion tuning.

Steel head and cap blocks are precision size, finished on all sides and are bored and grooved for concentric alignment of mating parts.

Hardened washers under each tie rod nut prevent galling, ensuring correct tie rod pre-stress and pressure envelope integrity.
