1.1 Forged brass: Strength and no porosity equals long life. Higher hydrostatic pressures, safety and performance. 1.2 Intel and Discharge Ports: Heavy bosses for added strength. Offset discharge ports: High efficiency, smooth flow. 1.3 Bolts : Eight bolts: 6mm, grade 12.9
2.1 Ultra form cages: Durability, strength and long life. 2.2 Poppets, seat and spring: 303 and 400 series stainless steel. 2.3 Valve caps: Machined brass – greater strength.
3.1 High pressure packing: “V” style (D-1) Buna-N (cotton duct weave base) strong and tightens under load. 3.2 Low pressure seals: “U” cup double lip Buna-N, good positive seal. 3.3 Support Guides: Machined brass, two-piece construction to assure proper plunger alignment and to maximize packing and seal life.
Oversized for maximum life and load disbursement, needle bearing on the drive side and ball on the non-drive side.
