OEM Accepted API 100% Virgin Tungsten Carbide Ball&Seat Blank/ Rough grinded/ Polished
Product Description
The hard alloy balls&seats valve is evolved from the traditional plug valve. Its opening and closing member is a sphere, and the purpose of opening and closing is achieved by the sphere around the axis of the valve stem.The ball-and-seat assembly is a key component in the subsurface pump. It probably undergoes more severe service on a continuous basis than any other component because even a slight amount of wear on the ball or seat will cause an immediate loss of pumping efficiency.Our ball-and-seat valves are designed and manufactured according to API 11AX Specification for Subsurface Sucker Rod Pumps and Fittings (current edition). Each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.
