Wilesco 01593 Steam Supply Valve For D16 D18 D20 D22 D24 T90

Wilesco 01593 Steam Supply Valve (Valve‑Body Base Not Included)

Wilesco part number: 01593

Overview

The Wilesco 01593 is an authentic steam shut‑off and drain valve assembly, supplied without the valve‑body base.

This replacement part fits seamlessly into Wilesco engine models D16, D18, D20, D22, D24, and T90, serving as a key component in regulating steam flow and easing boiler maintenance

If your steam engine’s shut‑off valve is worn, leaking, or stuck, replacing the valve alone can restore proper regulation without the need to replace the entire base assembly. This approach is cost‑efficient and helps extend the engine’s lifespan while preserving original components.

Installation Notes

• Ensure the boiler is fully cooled and depressurised before working on valve components.

• Retain or reuse the existing valve‑body base and sealing ring if still undamaged.

• Thread in the new valve and tighten carefully, avoiding over‑torquing to preserve thread integrity.

• After installation, test under low pressure to verify a tight, leak‑free seal.
