- Key Products/Technologies
- Rotary Unions: An extensive range of rotary unions for articulation oscillation movement. The DNRF series features PN10/PN16 flanged connections, carbon steel with Kanigen® or 316L stainless steel, reduced production costs, easier maintenance, and lower starting and operating torque. The DWPA series is designed for offset printing and plastics markets, suitable for cooling or transferring water and non-corrosive fluids, with aluminum and stainless steel components, single or double passages, balanced mechanical seals, double-ball bearing precision, drainage holes, and interchangeable cartridges. The 9000 series offers NPT connections, carbon steel or stainless steel construction, and a bellows sealing system, suitable for water, steam, and hot oils, with pressure resistance up to 250 psi. Other series include DWA, 5000, 8000, 1000, 3SBP, DNHC, DNCHPR, DNCHP, and DNTP.Rotary Unions: An extensive range of rotary unions for articulation oscillation movement.

- Rotary Seals: Includes sliding ring seals for rotating shafts. Offers various types such as high-pressure, low-pressure (single/double/special lip seals), sliding seals, gearbox seals, chemical seals, high-temperature seals, stainless steel seals, pneumatic seals, shaft seals, U-shaped seals, double-acting seals, industrial seals, and custom-made seals. VR radial sealing rings for rotating shafts feature low torque, compatibility with standard or stainless steel shafts, high non-concentricity (up to 0.4mm), low friction and heat build-up, and compatibility with various fluids. Materials include stainless steel, elastomeric, PTFE, and FPM, with specifications ranging from -50°C to 300°C, 0 to 15 bar pressure, 6mm to 380mm diameter, and 0 to 40 m/s speed.Rotary Seals: Includes sliding ring seals for rotating shafts.

- Check Valves: Includes ball check valves (40 series) and piston check valves (4000M, 4000MEC). Applicable for various fluids such as water, gas, oil, compressed air, and steam. Constructed from chemical nickel plated steel or 316L stainless steel. Offers metal/metal or metal/rubber (Nitrile, Viton®, E.P.D.M.) sealing options for complete tightness. The guided plug with a synthetic rubber seal prevents flow reversal and protects circuits from overpressure.Check Valves: Includes ball check valves (40 series) and piston check valves (4000M, 4000MEC).
