Paper: The Petrovalve Plus An Innovation In Sucker Rod Pump Valve Technology

The Petrovalve technology eliminates the high failure rate and low efficiency inherent to the traditional ball and seat valve configuration which has been in use for the last 70 years. These improvements are due to the guided seating surfaces of the Petrovalve design, providing some exciting opportunities for producing oil companies through both material selection and operating variables. With a larger flow area and less pressure drop across the valve, the Petrovalve design allows for increased pump efficiency. Production increases of 35% are not uncommon in the field. Eliminating gas lock problems common to many thermal and non-thermal well pumping operations is the Petrovalve Gas Breaker. The traveling valve automatically opens at the end of each cycle allowing the hydrostatic fluid to flow through and exchange any trapped gas accumulations. Available in cast cobalt alloy (stellite), tungsten carbide, and titanium carbide, the whole line of Petrovalve products offers increased production and decreased maintenance costs and downtime. Through greater pump efficiency and the versatility to operate at deviated angles, right through to the horizontal, oil producers see a direct effect on the bottom line.
