    ISO High pressure solenoid valve

    Hi guys. I’ve searched all over for a solenoid valve and have only come up with one from Magnatrol, but i need another option. I’ve found a few others but they all require a minimum differential pressure to operate, but i need it to be operational with 0 psid. I’ve considered a pneumatically...

    A threaded stud through the base plate with spherical washers is what I've generally seen.

    Calculating air velocity due to pressure in a tank

    Depending on which flow equation you use, it'll be between 250 and 350 mph.

    tie- in joint in piping system

    The main purpose of hydrotesting is to ensure the integrity of the pipe, not necessarily the welded joints. As long as the joints were weleded, inspected, and NDT'd correctly, then a joint failure is unlikely.

    recip compress blowdown on esd

    The only time we blowdown any of our recip units is for maintenance or a station ESD (emergency), or for the rare case like BigInch described where the starting torque is too much for the engine starters to handle, then we just do a partial blowdown and re-pressurized to line pressure after...

    Compressed air dryers at high altitudes

    It's a sealed system. So, the atmospheric pressure will only affect what you see in the system's indicated gauge pressures (i.e. compressor discharge and suction gauge pressures will be higher than they would be at sea level). The internal thermodynamics of the refrigerant system will remain...

    recip compress blowdown on esd

    Agreeed. There's never useless information provided by you, David or anyone here. I meant useless in terms of trying to accuralely answer, what appears to be, an ambigious, unclear question from the OP.

    recip compress blowdown on esd

    I think the OP is confusing the issue by referring to "esd" in the title, but then talking about "trips" in his question, which apprently "always happens". So his trips are probably normal nuisance shutdowns, and not really ESD's. I don't know, but this thread is useless without him being...

    Help needed, Reciprocating compresso

    Was there a torsional analysis performed on this setup? Torsional vibration is usually a silent killer and not generally detectable with normal vibration equipment, but since you have a gear box with allowed a modicum amount of torsional play available, it may be manifesting itself as gear...

    Actuator Retrofitting (Existing Actuator with a new valve)

    You should be fine re-using that actuator. But like gerhardl said above, the most important thing is to ensure the mechanical stops are set on the actuator, such that they limit the valve's movement, not the valve's stops, otherwise you'll likely break the valve stop, shear a pin, or something...
