Valve springs keep valves firmly seated in the socket.
The valve spring is the spring that closes the valve in the engine head after the cam lobe or rocker opens it . If the valve didn't close, many things would happen , the main one being the motor would not fire .
A solenoid valve is a valve controlled by an electrical coil. A spring keeps the valve closed. When power is turned on to the coil, a plunger is pulled, opening the valve.
As a direct relief valve opens, its spool or poppet pushes against a spring. As the spring compresses, the system pressure necessarily rises due to the spring constant. To handle large flows, you need a big valve. To minimize the pressure rise due to the spring constant you need a long spring. To minimize the pressure drop due to the valve body, you need a big valve body, which in turn needs a bigger spring. As the operating pressure goes up, you need stiffer (typically bigger)springs. Eventually the cost of the valve is prohibitive and a pilot operated valve is called for. There are benefits to using direct operated valves which may out weigh the costs, but most direct operated valves are limited to medium and low pressure settings.
Generally there's a spring holding the valve close, when the internal pressure is great enough, the valve opens - until the pressure drops. In some applications, there's a weight holding the valve closed.
To adjust the load sensor valve on a Navara ute after upgrading the spring, start by checking the valve's mounting position to ensure it's properly aligned with the new spring rate. You may need to adjust the linkage or the valve itself to ensure it accurately reflects the load. Additionally, consult the vehicle’s service manual for specific adjustments, as they may recommend changing the preload or repositioning the valve arm. Test drive the vehicle to confirm the load sensing system is functioning correctly with the new spring setup.
A valve spring "keeper" or AKA a valve spring "retainer" is used to lock a valve spring to the valve.
Valve pocketing is when a valve is hammering the valve seat.mostly due to miss adjusted valve spring/wrong valve spring/to strong of a valve spring or valve stem to short.Makes the valve seat deeper.
Yes, you remove the rockers, add air pressure in the cylinder through the plug hole and use a valve spring compressor to remove valve spring. You can now change the valve seal.
how many positions does a spring offset valve have
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.

u need remove cylynderhead then camshaft then rockerarms then use a valve spring compressor then change your valve rubbers.
The purpose of the valve spring is to maintain contact between the components in the valve train, so the valve motion will follow the cam profile.
Your engine will probably missfire and you will not have compression in the cylinder that has the broken valve spring because your valve will stay open.
Spring loaded safety valve.
A valve spring's job is to close a valve opened by a mechanical or pneumatic opening mechanism. The weaker the spring, the slower it will close the valve. This usually manifests itself by the valve 'floating' at higher RPM's. As a spring weakens, the RPM at which the valve 'floats' will decrease. In general, the valve will still operate at lower RPM's, but not at higher RPM's. To achieve higher RPM's, engines built for performance usually use stronger springs to return the valve as quickly as possible, to accommodate the reduced time available to close the valve. The tradeoff is that the valve is slammed against the seat harder soon wearing both out.
With a Valve Spring Height Micrometer ----------------------------------------------------------------- If you don't have one of these tools you can also use what is called a snap gauge. Snap gauges are spring loaded and you can use it to measure the distance from the spring pad to the bottom of the retainer. Then you can measure the end to end distance of the snap gauge with either a dial caliper or a micrometer. Not as fast as the first solution but it is all we had for many years.
