Ultimate Abrasion & Corrosion Protection For Harsh Flows
Robust ss316 stainless steel body with silicon carbide (sic) lining for superior wear resistance in abrasive slurries and corrosive media.
Ultimate Abrasion & Corrosion Protection For Harsh Flows
Robust ss316 stainless steel body with silicon carbide (sic) lining for superior wear resistance in abrasive slurries and corrosive media. swing or ball check design, flanged ends, pn16–pn100 pressure ratings.
The SS316 SiC-lined check valve combines the corrosion resistance of AISI 316 stainless steel with the extreme hardness and abrasion resistance of silicon carbide lining. This design prevents backflow in demanding environments where standard valves fail due to wear from slurries, chemicals, or particulates.
Available as swing check (for low-pressure, low-velocity) or ball check (for high-velocity), with bolted body for easy maintenance. SiC lining covers internal surfaces, seats, and discs for full protection.

316/316L stainless steel is widely used in chloride and chemical process environments due to its enhanced resistance to corrosion and pitting, attributed to its molybdenum content. These alloys offer excellent mechanical and corrosion-resistant properties across a range of temperatures and environments, making them essential in chemical processing, marine, and high-temperature industrial applications.
Low carbon version of 316, offering superior resistance to intergranular corrosion after welding. Commonly used in marine and chloride-rich environments. Excellent weldability without post-weld annealing.
High carbon content variant suitable for elevated temperature service. Offers greater short and long-term creep strength. Commonly used in high-stress boiler or furnace applications.
Standard molybdenum-bearing austenitic stainless steel. Excellent resistance to chlorides and moderate acids. Widely used across various chemical and process industries.

Understanding the differences between reaction bonded and pressureless sintered silicon carbide
Reaction bonded silicon carbide offers the lowest cost production technique with excellent overall performance characteristics.
Beams, rollers, cooling air pipes, thermocouple protection pipes, temperature measurement pipes, burner nozzles, wear-resistant parts, corrosion-resistant parts, sealing parts, and various special-shaped structural parts.
Compared with reaction bonded silicon carbide, pressureless sintered silicon carbide offers superior performance in demanding applications.
Can be used in environments where other materials cannot meet requirements, offering significantly longer service life and reduced maintenance costs.
