China API Valve Balls Seats Sucker Rod Pump Valve Balls Seats Cobalt Alloy Valve Balls

API V11Industrial Brake -225 Stellite Valve Balls and Valve SeatsOur ball-and-seat valves are designed and manufactured according toAPI 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.Available materials and qualities to be used in assemblies of the same or combined materials are as follows:1.Stainless Steel:API symbol A12.Cobalt Alloy:API symbol B23.Tungsten CaLED Video Processor rbide:API symbol C14.Nickel Carbide:API symbol C25.Titanium Carbide:API symbol C36.CeramicThe following materials are available in ball and seat sets with the ball and seat being the same material or a combination of materials.Cobalt, chromium and tungsten alloy with high corrosion and abrasion resistant properties. The ball hardness is HRC 58-61 and the seat hardness is HRC 52-56 and is essentially nonmagnetic. DuMore® is recommended for all hard pumping conditions with abrasive and corrosive fluids.
Combination Assemblies:The above materials are offerPipe Fittings ed in various ball-and-seat combination.Specifications of Valve Ball & Valve Seat for API Sucker Rod Pump: Item

Tungsten Carbide is the hardest and toughest ball and seat material available. It has the best abrasion and impact resistance of all ball and seat materials and has good corrosion resistance. Nickel Carbide is almost as hard and tough as Tungsten Carbide and has better corrosion resistance. Titanium Carbide is offered as a ball material and has about the same hardness and toughness as Nickel Carbide with the same weight.
Standard Stainless is the most popular ball and seat material due to its good corrosion resistance and economic price. It is made from 440C stainless steel and heat treated and tempered to a hardness of HRC 52-56. It is recommended for mild corrosion and abrasion in moderately deep wells.
