Check Valves have an extended use in many industrial applications such as Oil & Gas, chemical and petrochemical plants, thermal applications, fertilizer plants, etc… These valves can withstand pressure up to class 2500# and can de designed with soft or metal seat. These valves allow fluid circulating in one direction, preventing reversal flow in horizontal pipelines. They have the ability to react quickly and automatically to direction changing.
According to different check valves designs, the seat can be achieved by a spring or its own disc weight. In some cases, a counterweight can be installed to minimize the water hammer effect and improve the valve performance and response.
