Cla-Val 90G-21 / 90A-21 Fire Protection Pressure Reducing Valve

Pilot-operated pressure reducing valve in globe (90G-21) and angle (90A-21) patterns that holds a steady downstream pressure in fire protection systems.

Brand

Cla-Val

Product Details

Product Overview

The Cla-Val Model 90-21 is an accurate, pilot-operated regulator that reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate or varying inlet pressure. When downstream pressure exceeds the pilot setting, the main valve and pilot close drip-tight. With the optional check feature, a pressure reversal closes the valve to prevent return flow.

Key features

Globe (90G-21) and angle (90A-21) patterns
Dual guided stem for reliable seating
Tapered metal seat for drip-tight shut-off with replaceable 316 stainless steel seat
Single internal guided assembly with in-line maintenance
Proven repeat functionality in harsh conditions

Typical applications

Fire pump discharge regulation, pressure zones in high-rise standpipe and sprinkler systems, and system pressure regulation where downstream equipment must stay within its rated pressure.

Applications and Building Types

The Cla-Val 90G-21 and 90A-21 pilot-operated pressure reducing valves are engineered to hold steady downstream pressure within fire protection systems. These valves are essential for regulating pressure in high-rise standpipe and sprinkler networks, ensuring that downstream equipment remains within its rated limits. They are also widely used for fire pump discharge regulation and in various pressure zones where consistent flow control is critical for system integrity and safety compliance in Saudi Arabia.

Key Technical Features

Available in globe (90G-21) and angle (90A-21) patterns to suit different installation requirements.
Features a dual guided stem for reliable seating and consistent performance.
Equipped with a tapered metal seat for drip-tight shut-off, including a replaceable 316 stainless steel seat.
Utilizes a single internal guided assembly that allows for in-line maintenance without full system isolation.
Includes an optional check feature that closes the valve to prevent return flow during pressure reversal.
Provides proven repeat functionality even in harsh operating conditions, maintaining accurate pressure reduction regardless of varying inlet pressure or flow rates.
