Solenoid actuated valvesseries K with rotatable coil for temperatures from -40 to +80°C |
|
| Indirectly operated valve of the K series, which has not only a large flow rate, a long service life but also better availability. The basic feature of this valve is the possibility of use at temperatures from -40 to +80°C. The valves can be used separately or mounted on a base plate as a group assembly. The connector is supplied only with a cable and must be ordered separately. The connector connection to the coil complies with the DIN 72585 standard, used in the automotive industry. Valves series K contains spool and sleeve assembly, which guarantee long lifetime of valve. |
| We make the spool and sleeve assembly from hardened stainless steel. The technical interest is that thanks to the precise grinding and honing of both parts, such accuracy is achieved that the spool in the sleeve moves on the air cushion. This essentially eliminates possible wear and at the same time can be moved very easily and very quickly with the piston. The clearance is so small that there are no leaks even without a seal. |

Conversion of internal to external air pilot supply
External air pilot supply is used, when air supply pressure is lower than 0,15 MPa (1,5 bar), when air supply pressure is higher than 1,0 MPa (10 bar) as well as for vacuum and or if another medium than compressed air is used. In such cases, it is necessary to change the standard setting, where the air for auxiliary control is taken directly from the supply (1) of the valve.
| When converting from internal to external pilot supply, please proceed as follows: | ||
|
1) Dismount connector lid with pilot valve, pay attention to the O-ring between the cover and the valve body insert it into the hole with the O-ring in the lid, check if the O-rings fits correctly in the lid and put the lid back (tightening torque 1.5 Nm), insert and fasten the connector modified compressed air with pressure 0,1 to 1,0 MPa |
