The Various Types Of Cylinder Valves

By Cornelia White


There are various types of cylinder valves used in our homes and also the cars we drive. The braking system of a car consists of a master cylinder which contains various regulators for controlling the fluid used in the system. Care must be taken when purchasing or replacing a new regulator in a car since a fault or a leak in the system can cause a very terrible accident.

The regulator used in our homes is used to control the gas we cook with from the supply pipes. When buying one you need to be very careful since a leakage in it can lead to a very serious fire. That way, care must be exercised.

The major container in a car consists of several types of regulators. All these have their various attributes and functions which must be in place for a car to work effectively. The basic type is known as the combination regulator. This one is usually found in cars which have both the frond and back drum breaks. This one mainly functions by serving a warning to the driver in case the braking system has an issue. It usually combines with three other regulators for its efficiency. The others include pressure, proportioning and metering regulators.

The metering regulator has the primary task of controlling the engagement of the disc and drum braking. The drum brakes should always be engaged first. It does not allow pressure into the disk brake until threshold pressure is attained. Threshold pressure is less than the maximum pressure in braking system hence allowing drum brakes to engage first before the disc brakes kick in.

The maximum pressure is way higher than the threshold pressure. This makes the drum breaks to engage barely prior to the disc breaks. This way, the stability of the vehicle is attained when one is braking.

The pressure differential regulator alerts you if there is a leakage in any of the brake circuits. It contains a piston in the middle of a tube and each side of the piston is exposed to pressure on both sides hence keeping it in the middle of a tube. If there is a leakage in any side, the pressure will drop on that side making it off center. This closes a switch which turns on the light on the instrumental panel on the dashboard.

This will close a switch which in turn turns on light on the instruction panel on dashboard of vehicles. This alarms the driver on the need for repair. This acts as a safety measure. The proportioning regulator control the amount of pressure applied between the front disc and the rear drums. It reduces amount of pressure applied on the rear brakes. This makes the front disc brakes apply more force.

The other types of regulators are used in our homes to control gas leaving the cylinders or the supply pipes. Gas in these cylinders is always subjecting to a very high pressure. Thus, the role of the regulator is to reduce the amount of gas to the level which is favorable to a gas cooker.

The spring valve work hand in hand with the diaphragm chambers which are gas filled on the downstream end. The downstream pressure goes down; the spring valve is pushed to give more room for gas to get inside. This is how cylinder valves work.
