Oil and gas production and processing can and does produce some nasty gases, when mixed with water they can be corrosive and when released to the atmosphere are toxic.
With any moving part there are issues with containment of such gases and when higher pressures are added the need to work to very high tolerances is critical.
Surface finishes must be perfect and technological advancement in modern materials is continuous to match the demands of zero emissions combined with high pressures, broad fluctuations in temperature and corrosive conditions.
BEL Valves goal to achieve zero emissions has facilitated the development of our patented metal to metal stem seal design, and in house control of our Tungsten Carbide coating facility guarantee exceptional surface finishes and therefore accurate sealing faces.
