Tungsten Carbide Valve Seat

Tungsten carbide valve seats are designed to withstand extreme working conditions involving high pressure, high temperature, and severe abrasion. Made from hard carbide materials, they are ideal for oil & gas equipment, chemical systems, diesel engines, and high-pressure pumps.

As a professional tungsten carbide parts manufacturer, we XYMJ offers a wide range of standard and customized valve seat solutions to meet diverse industrial demands.

Types Of Tungsten Carbide Valve Seat

Tungsten carbide valve seats can be categorized into several structural types based on their sealing geometry and application requirements.

Flat Valve Seat

Flat valve seats possess a flat seat surface with a linear contact between the valve disc or plate. The design is appropriate for medium to low pressure applications where fluid control is achieved through flat surface sealing.

Because of its high density and corrosion resistance, flat valve seats give reliable sealing and a longer service life, over five times that of conventional materials. Sealing is accomplished by pre-tightening force between the valve plate and the seat.

Conical Valve Seat

Conical valve seats have a conical sealing surface that is matched with a conical valve core. The structure decreases fluid turbulence as well as the impact of particles and can be applied in high-pressure, high-temperature, and corrosive media. Conical seats are widely used in severe-service industrial systems where enhanced flow stability and sealing performance are required.

Spherical Valve Seat

Spherical valve seats are designed to mate with an annular sealing member or a spherical ball. Due to the geometric nature of the sphere, stress is distributed equally, thus improving sealing life and efficiency. These seats are used in rod-type and tubular oilfield pumps where reliable fluid control and long service life are required.

Why Choose Valve Seat with Tungsten Carbide?

Choosing tungsten carbide as the material for valve seats offers significant advantages in performance, reliability, and service life, especially in harsh working conditions.

Extreme Heat and Hardness Resistance

With tungsten carbide, these seats stay dimensionally stable at 500 °C and maintain high hardness even at 1000 °C, making them ideal for high-temperature, high-load applications.

Exceptional Wear and Corrosion Resistance

The exceptional hardness of tungsten carbide,orders of magnitude greater than most standard metals, ensures valve seats can maintain sealing performance over extended periods, even in erosive or high-friction applications.

Precision Machining for Leak-Free Performance

Manufactured with tight tolerances and smooth sealing surfaces, they ensure reliable sealing and consistent performance in critical fluid control systems.
