ValvTechnologies Europe received a call from a Oil and Gas client with a leaking `14″ Neles metal seated ball valve on critical service duty. Upon inspection it was apparent the ball and seats were badly scored and we need to react very quickly to restore sealing surfaces and re-certify. The original stack height was measured for the ball and items were stripped and chrome removed. Two new thicker seats were manufactured to compensate for the loss in stack height. We then re-coated the ball and seats with tungsten carbide and matched the seats to a sealing set.
