K23D-1.2T DIN4.8 Pneumatic Solenoid Coil
This K23D-1.2T DIN4.8 Pneumatic Solenoid Coil is suitable for the K23D series two-position three-way Pneumatic Solenoid Valve. The K23D series miniature Solenoid Valve is the basic component in the pneumatic transmission system. It is often used as the pilot control of the large-volume reversing valve. It is also called the electromagnetic pilot valve. It can also directly control the actuator with low air consumption. The quality of the coil determines the performance of the reversing valve.
1. Commutation performance
Under the specified working conditions, can the solenoid valve be reliably reversible after being energized, and can be reliably reset after the power is turned off.
2. Commutation and reset time
The time required from the energization of the electromagnet to the end of the spool reversal, the reset time is the time from the electromagnetic de-energization to the return of the spool to the initial position.
3. Commutation frequency
The maximum number of commutations allowed per unit of time.
4. Service life
Solenoid valves are used to damage major components, failing to perform normal commutation and resetting operations, or using the number of commutations that their main performance indicators have significantly deteriorated beyond the specified specifications.

Reversing valve malfunction
1. The reversing valve does not move.
Cause: The air source pressure is insufficient; the actuator is faulty; there is foreign matter in the valve; the valve internals at high temperature are stuck.
Solution: Check the air supply, restore the pressure; check the spring force of the actuator and the spring breakage and the diaphragm is damaged (Pneumatic Valve); check the signal; disassemble the valve, check and repair.
2. Inverted valve stroke is insufficient
Cause: The positioner is not calibrated and the stroke is not adjusted properly; the actuator spring rating is too small; there is foreign matter in the valve.
Solution: Re-adjust the positioner; adjust the spring; remove the valve to remove foreign objects.
3. The reversing valve is slow
Cause: The packing is too tight or the packing deteriorates; the valve stem is not straight, misaligned, causing large friction; the pressure of the air source is small.
Solution: Restore the supply air pressure; replace the repaired packing or stem.
Reversing valve leakage
1. The valve is leaking and the stem length is not suitable.
The reason for the leakage inside the valve: the air opening valve, the valve stem is too long and the valve stem is too short, the distance of the valve stem is up (or down) is not enough, causing a gap between the valve core and the valve seat, which cannot be fully contacted, resulting in closing Not strict and leaking.
Solution: The valve stem should be shortened (or extended) so that the stem length is appropriate so that it is no longer leaking.
2. Filler leakage
Reasons for filler leakage:
(1) The packing is in close contact with the valve stem after loading the stuffing box, but the contact is not very uniform, some parts are loosely contacted, some parts are tightly contacted, and some parts are not in contact.
(2) There is relative movement between the valve stem and the packing. As the medium with high temperature and high pressure and strong permeability is affected, the packing leaks.
(3) The contact pressure of the filler is gradually attenuated, and the medium itself leaks from the gap due to the filler itself.
Solutions:
(1) In order to facilitate the filling of the packing, the top of the stuffing box is chamfered, and a metal guard ring with a small erosion-resistant gap is placed at the bottom of the stuffing box to prevent the packing from being washed by the medium.
(2) The contact surface of the stuffing box and the filler should be smooth to reduce the wear of the filler.
(3) Flexible graphite is selected as the filler, which has the characteristics of good air tightness, small friction, small deformation, and no change in friction after retightening.
