  • An Overview of Thermoplastic Valves and Their Performance
    Thermoplastic valves offer a dependable and economical way to handle corrosive chemicals in some of the harshest environments. When comparing nonmetallic valves to metal valves there are many criteria the specifier must consider, including: process pressure, temperature boundaries (high and low
  • Traditional solenoid valves are simple to install but may not be the right solution for long term reliability or high flow applications
    and causes low flows. Additionally, the diaphragm generally has within it a very small pilot hole to allow pressure to equalize on both sides of the diaphragm. The pilot hole easily clogs causing the solenoid valve to function erratically. Smaller solenoid valves and high pressure solenoid valves use
  • All-Metal Valves: Angle and Inline Specifications
    MDC bakeable all-metal angle and inline valves are designed for use in ultrahigh vacuum environments where elevated temperatures preclude the use of elastomers and low temperature gasket metals. These valves provide reliable high temperature seals from atmospheric pressures to below 10-11 Torr.
  • How to Choose the Right Size Air Release Valve
    during the filling or draining of a piping system. Air comes out of solution in a pipeline because of low-pressure zones created by partially open valves, variations in flow velocity and changes in pipeline system elevation. An air pocket in system high points may reduce the flow of water
  • Severe Service Valve (SSV) Solves Complex Problems
    PotashCorp needed to automate a positive displacement pumping system which would require a control valve to operate at a continuous high pressure differential. The discharge piping in their mine rises over 1000 meters to the surface, so the operating pressure can vary significantly based
  • Industry Solutions For The Most Common Solenoid Valve Challenges
    the parts is created. The leakage typically starts off small and can escalate to a high leakage rate depending on the process fluid and pressure of the fluid. Due to the liquid traveling at high velocities through the leakage path, it can erode the sealing surface. To eliminate leakage caused by foreign
  • Synchronized pressure measurement in industrial piping system
    High pressure piping requires precise absolute pressure measurement as well as the ability to record fast transients. Peaks in pipe pressure can ultimately cause valve or joint failures, therefore the pressure needs to be closely monitored. The biggest challenge of such a measurement project
  • Application Note: Oil & Gas - SAGD Steam Injection & Letdown Valves
    The majority of SAGD facilities will use once-through steam generators (OTSG) for their steam production. The steam from these OTSGs is piped to steam letdown valves, which drop the pressure to injection valves that inject the steam into the well pad. The steam pressures are quite high

  • Handbook of Diesel Engines
    Low pressure and high pressure valves control the pressure in the accumulator.
  • ISA CNTRL VALVES - Control Valves
    Many high pressure valves installed for elevated temperature service include bonnet extensions as a secondary design feature.
  • Manual combustion engine
    In the currentless state, the high pressure valve through spring force is opened; thereby, the pumping region of radial pistons can be filled with fuel over the low pressure circulation.
