Hydrobar Downstream

• RYL valves are 100% hydraulically operated control valves that maintain and stabilize the downstream pressure at a constant value regardless of flow demands and variation in downstream pressure. Normally equipped with visual position indicators, body made of ductile iron with epoxy coating and internal parts of stainless steel.
• The valve is designed to reduce pressure loss, noise and damage associated with cavitation. The RYL control valve of the XLC S series is completely modular and can be used for a wide range of applications
• Epoxy coating according to FBT technology, blue color RAL 5005.
• Application internal and external with a minimum coating thickness of 250 μm.
• Epoxy coating, approved for drinking water, electrostatically applied according to DIN 3476-1.
• Compliance with standards: Tested according to EN 12266. Face-to-face dimensions ISO 5752-1. 
• Approval: ACS (Certificate of Health Conformity). 

Sizing information:

• Upstream, downstream pressure and flow are necessary for correct sizing.
• The AC anti-cavitation device is recommended for resistance against cavitation and precise regulation in low flow cases .
• A minimum length of 3 DN upstream of the valve is recommended for better precision.

Downstream driver adjustment ranges:

• Blue spring: from 0.7 to 7 bars.< /li>
• Red spring: from 1.5 to 15 bars.
• Higher values ​​up to 25 bars on request.
• Values ​​lower than 0.7 bars available with high sensitivity drivers.

Conditions of use:

• Maximum temperature: 70°C.
• Minimum operating pressure: 0.7 bar.
• Maximum operating pressure: 25 bars .
