Q: How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks: save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar

Q: Are fire fighting signal valves and signal butterfly valves the same thing?: The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.

Q: The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30: 1, this is a good question, it seems that this has not yet made a unified standard requirements, a bit confused2, personal understanding of fire water supply pipe, pipe shall be installed on the valve, because the valve is fully open all closed features of fire control system is usually required is fully open, easy management features are obvious.3, fire water supply system is also useful to butterfly valve, but mainly signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.

Q: How do hydraulic butterfly valves work?: The valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. Sorry, the picture doesn't come up

Q: What are the functions and uses of butterfly valves?: Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.

Q: Types of butterfly valves: Butterfly valve structure categories: central to clip butterfly valve, central flange butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, eccentric butterfly valve, soft sealing butterfly valve, hard sealing butterfly valveButterfly drive categories: handle, worm gear, electric, pneumatic, electromagnetic, electromagnetic, hydraulic, electro hydraulic, hydraulic, hydraulic, pneumatic

Q: can't locate freon intake valve for 03 jaguar an was wondering were it is located at: There is no Freon intake valve for an 03 Jaguar. Freon is R12 refrigerant and the vehicle uses an R134a refrigerant system. There is also no such thing as an intake valve on any vehicle refrigerant system. There is a high pressure port and a low pressure port. To answer your question: under the hood. Any other information would likely endanger your life, since this is obviously a DIY question and you lack the knowledge to safely recharge your vehicle's refrigerant system. R134a refrigerant, if inhaled, can kill you. Do not turn a DIY project into a DIE project. Leave the complicated stuff to the professionals.

Q: Which is better, the round two lobe butterfly valve?: Can be directly installed in the ventilation pipe, connected with the wind pipe, used to control the speed, adjust the indoor air, the double structure diagram can reduce the space length of the blade is unfolded, and also has the characteristics of small airflow resistance, convenient adjustment etc.
