0290 Solenoid Valve Installation And Operating Instructions.pdf

operating instructions for a Type 0290, 2-way solenoid valve that is normally closed (Circuit function A). It specifies seal materials and fluids handled, with details in accompanying tables. The maximum inlet pressure is indicated on the valve label, and no pressure differential between ports is required.

Installation guidelines include ensuring piping is free of foreign matter, using PTFE tape for sealing, and installing the coil uppermost to prevent debris accumulation in the pilot valve. A strainer should be placed upstream to protect against foreign materials. The pipework must support the valve body without strain, avoiding blockages at the pilot bore.

Markings include body material (Brass or Stainless Steel) and seal material (EPDM, NBR, FKM). Specifications such as voltage/frequency/power consumption, maximum pressure, and fluid/ambient temperature ranges are provided. The product is made in Germany with specific item numbers and configurations.

Electrical connections must match the label specifications, with a ±10% voltage tolerance. For UL-listed, CSA-approved, or FM-approved use in hazardous locations, it requires a type 2509 cable plug connector. Intrinsically safe applications require clear marking and correct polarity connection.

Troubleshooting involves checking port connections, operating pressure differential, supply voltage, and ensuring the pilot hole and bore are unobstructed. Core issues may indicate short circuits or coil burn-out. The terminal screw torque for type 2509 is specified at 0.5 Nm.

Warnings emphasize user responsibility in selecting appropriate models and installation by qualified personnel. Specifications should not be exceeded, and changes to the product void warranties.
