High Performance Tungsten Carbide Gate With Anti-Wear Hard Facing
Gate valves or sluice valves are widely used within the oil and gas sectors to control the flow of fluids and gases.They are rarely used to regulate the flow,more commonly,they are a simple but effective way of either shutting off flow,or fully opening to allow maximum unobstructed flow.
Gate valves contain a tungsten carbide coated slab and this will have a hole in it to allow the flow of fluid or gas when open, and also a solid area which blocks the opening either side of the slab when closed.The slab moves up and down to open and close with tungsten carbide coated seats within the body of the valve to maintain a seal that stops the fluid or gas leaking into the body of the valve.
As the seats and alab are both hard faced with tungsten carbide.It is critical that they are perfectly flat.Two perfectly flat surfaces will form a seal that will not leak,but producing the flatness required on tungsten carbide can be difficult,particularly as the specifications become tighter and tighter as valves are designed to handle higher and higher pressures.
