Kromschroder Fine-adjusting valve VMV1-05P 88013032

The Kromschroder VMV1-05P is a fine-adjusting valve with SKU 88013032, designed for precise manual adjustment of gas or air flow. It has a nominal diameter of 15 mm and a connection thread of Rp 1/2. The valve operates at a maximum inlet pressure of 500 mbar and within a temperature range of -10 to 60 °C. Its linear flow characteristic allows accurate flow setting, and the self-locking thread prevents accidental adjustment. The body is made of aluminium or brass.

Parts of this type are selected by matching the connection thread size and pressure rating to the existing gas train. The valve must be compatible with the gas type and the burner control logic. Installation involves checking the pipe thread and ensuring the valve is oriented correctly for flow direction. The adjustment mechanism should be accessible for manual operation.

Typical failure modes include leakage past the seat when fully closed, indicating wear of the valve seat or spindle seal. Equipment may exhibit unstable combustion or inability to maintain the desired fuel/air ratio. Check for gas leaks around the adjustment spindle and verify the valve closes completely.
