Solve Your "where can i find pilot valve for gas air" my compressor is a Rigid gp90135 i need the pilot valve and the troutle control.

That is not normal. The gas pilots need to stay burning, need pilot flame sensors too for the main gas valve in the oven to work. Who knows how the oven is set up that it all seems wrong now.
If there were a electric gas valve, the valve would be on fire and/ or seismic shut off. If fans were interlocked, it would be on fire cut off along with fire dampers.
Why would anyone control a gas valve cut off with exhaust fans? Goofy set up unless there is more to it. For now I would keep the gas on, independently from the exhaust fans, keep pilots lit and a pilot light flame sensor for oven gas valve/thermostat safety control.
Keep your oven Fromm filling with gas and suddenly igniting accidently before anyone gets hurt or there is property damage.

Your compressor is made by Hitachi. The pilot valve is what controls the engine and the pressure. Most likely the pilot is set to idle engine at 125 psi. The pilot valve can be adjusted higher or lower depending on needs but not higher than say 140. As the pressure drops to about 80 psi the pilot will cut in the engine to refill the tank. Pilot and throttle controls are finicky and require constant tinkering and or parts replacement. Your compressor needs the pilot to control pressure however does not need the throttle control. You can set the engine on constant speed. Less trouble but uses little more gas. Just remove the throttle control from the pilot and plug the hole. If the bad part is the pilot itself you will need to replace it. The new pilot will be adjusted to about 125 psi. Good luck with your repair

Several things can cause the problem you're having.

1. Low gas pressure due to a near empty tank or the heaters regulator is locked up and only
allows a small amount of gas to get the pilot. To solve this, turn the gas tank valve OFF & dis-
connect the hose from the tank. Wait 5 minutes & reconnect the hose to the tank. Open the gas
valve VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, light the pilot
and hold the gas control valve in for 30 seconds to 60 seconds. After that time, release the control
valve knob. Did the pilot stay lit? If so, problem solved. If it didn't you will need to replace the
heater's Hose/Regulator Assembly. You can use the same one that's for a gas grill. And find it at
any hardware store or home center that sells grills and accessories for about $30.00.

2. The pilot is dirty and needs to be cleaned. Use a can of compressed air with a straw nozzle (like you clean your computer with) to blow out the pilot tip.

3. The thermocouple has failed and needs to be replaced. If this is the case, you can order a new thermocouple for Blue Rhino (1.800.762.1142) , the manufacturer of your Patio Heater.

I hope this helped you and thanks for choosing FixYa.

The pilot valve (brass valve with flip lever or pull ring ) is what controls the pressure. The link below will help you adjust the pressure lower than safety valve release pressure (the safety valve has a rated value printed on side, make sure that the valve is actually releasing at stated pressure ). The pilot should be set to 135 ~ 90. A faulty safety valve will release pressure at lower that stated valve. Replace as needed. The link below is adjustment of a generic pilot valve, however the adjustment is the same on all brands of valves. Good luck

The pilot valve controls the pressure, idles the engine when set pressure is obtained and releases compressed air thru small vent while the engine is idling. If the idle is set too low, the engine may stall. Try increasing idle speed and make sure that when set pressure is reached that air is venting from pilot muffler vent. The pilot valve can be easily tested. With engine off and pressure in tank, flip the pilot valve start lever up then down. When flipped up, the throttle control shuld activate idle and the pull rope should be easy to pull. With lever down, throttle is pulled on engine and compressor is loaded making the rope very difficult to pull. If the engine stalls with air in the tank flip lever up to easily start engine then down to pump. Good holidays

You can use universal pilot valves and throttle control. Shop on ebay or www.grainger.com. Look closely at the fittings that are required to fit a different valve on your compressor. Most all pilot valves work the same however there are hundreds of fitting combinations. The throttle control is easier because they usually all have 1/8 thread into the pilot. Universal parts cost much less. I would suggest taking your compressor to a shop that specializes on air compressor repair and they could suggest what pilot would work best. Good holidays

There are two types of unloaders used on IR compressors. One is oil pressure controlled, and second is manually activated for starting. According to the photo and model number provided, yours is manually operated. Follow air line from compressor to tank. The pilot valve (brass valve) between airline and tank is a multi-function component. There is a flip leaver or pull ring w/ hold that unloads the compressor by venting air thru small muffler. The valve also contains the check-valve holding pressure in the tank, a means of adjusting pressure and controlls throttle for engine. For easy start, flip leaver upright and start; to run, flip leaver to right angle of stem.

the pilot valve or control valve when it unloads sends a air signal to close the motor throttle down to idle and depending on what form of control it uses for the compressor it will either use head unloaders to hold open the inlet valves or a unloader that dumps the compressor output to atmosphere, this one uses a silencer mounted near the pilot valve. if it uses this type remove the silencer and retest the operation. either you have a motor that is out of adjustment or the compressor is not unloading!

Follow the copper airline that leads from the compressor to the tank and you will find the pilot valve. This brass valve controls the pressure setting and also controls the engine. There is a small flip lever on top of the pilot valve that unloads the compressor for easy starting when there is pressure in the tank. Raise the lever straight up for start and lay to side for normal run cycle. When the compressor fills tank to set level, the pilot valve pops and idles the engine. If engine stalls raise idle by turning the idle screw clockwise at the carb. The arm that you see under the tank is the governor control arm. To increase the engine speed when pumping turn speed control screw counter clockwise. Sometimes the throtle control cable must be adjusted by loosening the clamp that holds the cable (black cable) at the engine and pulling the cable back away from the clamp and re-clamp. Hope this helps, good luck.

You compressor has a pilot valve that controls the tank pressure and the speed of the engine. Locate the brass pilot valve, (It has a flip lever that unloads the compressor) you will notice that it has two locking nuts that allow for adjustment when loosened. Loosen the small lock nut and turn the upper-most part of the pilot valve out to reduce pressure, in to increase pressure. Hope this helps, enjoy.
