Tungsten carbide coating

Tungsten carbide coating (hardness HRC75-80) and nickel-based alloys (such as Ni60) are adhered to the metal substrate via high-velocity oxygen fuel spraying (HVOF) or laser cladding technology, resulting in high bonding strength and the ability to withstand high temperatures and pressures.

Dustproof and erosion-proof

The valve stem employs a multi-layer sealing and dustproof structure to prevent media intrusion and subsequent wear.

Bidirectional sealing

The symmetrical structure supports bidirectional flow, adapting to complex pipeline requirements.

Self-cleaning function

The streamlined flow channel and scraper-type valve seat design automatically remove particulate impurities from the medium, preventing blockage.
