The Auld Double Control Reducing Valve is ideal for applications requiring substantial pressure reductions, provided that the inlet pressure does not exceed 51 barG. This valve features a self-contained balance pipe, ensuring optimal performance with a closing pressure of +7% relative to the reduced pressure. Its balanced design remains unaffected by fluctuations in inlet pressure and responds instantly to changes in demand. The valve offers impressive reduced pressure accuracy of ±5% across a flow range from full flow down to 10% (with a turndown ratio of 10 to 1). Furthermore, its soft valve faces are well-suited for dead end conditions, and the single seat design facilitates precise control at low flow rates.

The Kunkle Bailey 707VD Safety Relief Valve, featuring a Female x Female design, boasts a top-guided mechanism that ensures a clear seat bore and excellent lift capabilities. This valve is certified to BS EN 4126 Part 1 (BS6759 pt 1:2:3) and is ideal for use with air and gas, steam and hot water (above 212°F / 100°C), as well as process liquids, depending on the specific model chosen. We will configure and test the valve according to your specifications, and upon request, we can provide a pressure test certificate before dispatch.

A marine storm valve is a specialised check valve designed for installation in a ship’s sewage or drainage systems. Its primary function is to prevent seawater from backflowing into the vessel, especially in heavy seas or when the ship is heeled. By serving as a barrier against flooding and contamination through overboard discharge pipes, marine storm valves play a crucial role in maritime safety.

Purpose of a Marine Storm Valve

• Prevents seawater ingress through overboard discharge openings.
• Facilitates the one-way flow of wastewater, bilge, or greywater out of the ship.
• Vital for sewage, greywater, and drainage systems located below the waterline.

We supply marine storm valves from a range of leading manufacturers. Please contact us to discuss your specific requirements.
