Explanation of Low Torque Operation In 2012, we modified the SV-150, 4-way valve to lower the shifting torque. This allows operation at elevated working pressures. The high torque became an issue with current Shear-Ram-Boosters when operating at 3000 psi hydraulic pressure and 80 psi minimum air pilot, which was marginal with a 4” actuator cylinder… Read More

If you have experimented with the regulated output range between the manual and the failsafe actuator operators, perhaps you have noticed that one can achieve a much higher output than the other. Perhaps you have been confused about whether you should buy the “HP” or the “LP” version to achieve your BOP control system’s pressure… Read More

Hydraulic manifolds are increasingly gaining traction and replacing plumbing networks in new builds. Engineers and equipment builders typically give reasons for this trend because manifolds significantly reduce a circuit’s footprint, maintenance costs, and design complexity. However, as implementation goes into effect, there have been noticeable improvements in fluid power performance, such as: less leaks, less… Read More

PacSeal Hydraulics’ linear LSV control valves are designed with ShearFlo® metal-to-metal sealing technology to ensure high cycle life and negligible internal leakage with superior contaminant resistance, making these valves perfectly suited for critical service applications in harsh and hazardous environments. Although the LSV was originally designed for grease injection of frac tree valves, any application… Read More

PacSeal Hydraulics offers six different SV directional control valve sizes (SV-12, SV-25, SV-50, SV-100, SV-150, and SV-200) and eight different KR pressure regulator sizes (KR-12, KR-38, KR-75, KR-100, KR-140, KR-150, KR-175, and KR-200). As you can see below in Table 1 and Table 2, there is some overlap. In plain terms, the KR-38 can work… Read More

PacSeal Hydraulics’ hard seat relief valves are used in hydraulic control systems to protect the downstream circuit from over-pressurization* by a pump. Contrary to soft seated relief valves, they are metal seated for improved reliability and longevity in severe service conditions. The relief valves are also factory set for a specified cracking pressure (i.e. set… Read More

PacSeal Hydraulics’ hard seat check valves (also referred to as retention or reflux valves) are used in hydraulic control systems to prevent reverse transmission of pressure or to create unidirectional flow control. Check valves are commonly used to protect a pump or compressor by preventing the downstream stored energy in a hydraulic circuit from entering… Read More
