• How to Select a Pressure Relief Valve
  the valve is not doing what it is supposed to do. The first thing to determine is the type of pressure relief valve you are looking for. There are two common types of relief valves. One is the safety or pop off valve that opens completely when the set pressure is reached, diverting all, or almost all...
• Pressure Valves
  , when the accumulator is charged to the specified level, the pump unloads to tank. The unloading pressure of this type of valve is commonly determined by a spring-loaded spool; the spring can be adjusted to vary unloading pressure. Alternatively, the valves can be controlled by application of a pilot...
• Accumulators
  : gas loaded, spring loaded, or weight loaded. The latter are typically very large devices, with concrete disks loaded onto an oversized piston. Often found in older, high-demand applications such as steel mills, weight-loaded accumulators have a large capacity and uniform output pressure but present...

• Taking the Guesswork Out of Pneumatic Control
  actuated. If continuous cycling is required, use a selector or toggle valve at the input of the first step along with a valve that permits continuous cycle sequences. For applications that require the choice of selecting one cycle or continuous cycling, add a selector valve that determines the type...
• Quick-Action Couplers
  by the compatibility charts furnished by most coupler manufacturers. Many types of couplers are available but all have a few factors in common. Each coupler consists of two halves. Either half may contain a leakproof shutoff valve that closes automatically when the halves are separated, and opens when...
