Q:What is a Remote Operated valve ?
The term remote operated valve is slightly misleading, as it really means remotely controlled valve. Normally the valve actuator is mounted directly on the valve body so that it can open and close the valve. The majority of valves are either rotary ball or sliding gate type. Valve actuators can be operated by electrical methods, pneumatic or hydraulic, or by a combination. The most common types of actuator for industrial use are motorised electrical and pneumatic. Motorised valves will have a reversible motor for opening and closing, whilst pneumatic types will have a double acting cylinder with a 5 port 2 position or 3 position control valve. The control contactors and valves would be located in a control room, possibly controlled by a PLC or similar automation controller. In most cases position feedback will be supplied from the valve by means of limit switches to indicate its position, and in the case of motorised actuators, the running current can be monitored as an indicator of valve condition. If a pneumatic valve is jammed, the actuator will simply stall without damage, but for electrical actuators some form of overload protection is required to prevent excessive current load and overheating. The majority of industrial valves require little maintenance, but regular inspection for security, electrical connections, gland sealing etc should be scheduled at intervals suitable for the working environment.
Q:Ticking sound on 700 Grizzly...Valves?
They are correct. Well almost. The Rockers are what can be adjusted. They are too far away from the valve and are starting to hammer on them instead of just moving them. You will not cause immediate damage by riding it but you could wear out the rocker completely and drop a valve into the engine which would be very costly. Best to get it repaired soon. Make sure they install new rockers and springs. The main cause for this is poor oil maintenance or poor grade of oil being used. Always use a GOOD synthetic oil and your motor will last 10 times as long
Q:Are Valve, Infinity Ward and Activision going to fix the hacking in Call of Duty MW2 multiplayer?
Well first off Activision fired infinity ward so chances are slim to none (they hired Bungie, guys who created halo).. valve doesnt have a thing to do with the game and generally Activision are lazy asses so id count the chances around 1 in 100
Q:boiler bleed valve replacement?
It has been a long time since I have seen a system like that, but I believe you are correct. The knob on the opposite side of the bleed, is a flow control, which is used to adjust the amount of heat from the radiator. If you turn this all the way off, it should stop the water flow, providing it is not corroded. However, be careful when removing the bleed as the radiator will still have water in it. Try not to drown the neighbours.
Q:Tricupsid and bicupsid valves?
Bicuspid has to flaps and the tricuspid has 3 flaps
Q:Degreasing reed valve?
The flow of gasoline rushing past the reeds is enough to keep them clean. No degreasing is necessary. Are you sure you didn't hear de-carbonize the power valve? If so, remove the power valve and linkage from the cylinder. Remove hardened deposits with a wire wheel on a bench grinder. Clean the parts with parts cleaner.
Q:mitral valve prolapse syndrome?
the pain can relate to dysautonomia if it is persisting for long, even it can be a pleuritic pain otherwise, talk to your doctor about it.
Q:what is a flush valve? is it another name for a drop valve?
The proper names of the two valves in a typical home toilet are the flapper valve and the ballcock valve. The flapper valve sends water from the tank to the bowl during the flushing of the toilet. The ballcock refills the tank and also sends a small amount of water to the bowl during the flush.
Q:Who knows about pneumatic engine valves?
i don't!!! LOL LOL
Q:how do i open the power valves?
dude leave the power valves alone. you do not know what you are doing.
