Choke bean is often used in the positive choke valve for controlling the flow. Zonco choke bean is same as Cameron type H2 big john choke bean, body Material: 410SS, lined with Tungsten Carbide (YG8), to protect them from corrosive and abrasive wear.
On one side of the choke manifold, calibrated choke beans are used to control flow rate through the fixed choke box. Each bean is a specific diameter, usually in graduations of 1/64-1/32 inch, Depending on the type of equipment used, the size of the choke bean can be as large as 3 inches. The choke Bean in all standard API-6A available sizes.
Zonco has been specialized in customizing various kinds of non-standard tungsten carbide wear resistant components for more than 10 years. we are able to manufacturing all kinds of wear resistance valve parts based on customer's drawing and material requirement, support hardfacing process based on customer's technique requirement. since most of our products are customized and not suitable to show for other customer, welcome to contact us for OEM service.
