Brass Rubber Seated Swing Check Valves

Brass Rubber Seated Swing Check Valves are automatic non-return valves designed to prevent reverse flow in water, heating, and general mechanical pipework systems. They are widely used in plumbing, HVAC, and industrial installations where reliable backflow prevention and low-maintenance operation are required.

 
These valves operate using a hinged swing disc that opens with forward flow and closes automatically when flow reverses. The inclusion of a soft rubber (NBR) seat ensures a tight, quiet seal, improving leak resistance and reducing noise compared to metal-to-metal alternatives.

 
Manufactured from durable brass with BSP threaded connections, they are suitable for straightforward installation into standard pipework systems and are typically rated for PN16 pressures in smaller sizes.

Key Features

 
• Swing check (non-return) design for automatic backflow prevention
• Brass body construction for durability and corrosion resistance
• Soft NBR rubber seat for improved sealing performance and quiet operation
• BSP threaded connections for easy installation
• Full-flow design with low pressure loss when open
• Suitable for horizontal installation (vertical upward flow in some configurations)
• Pressure rating typically up to PN16 (size dependent)
• Temperature range typically around -10?C to 95?C (system dependent)

Key Benefits of Rubber Seated Design

• Tighter shut-off compared to metal seat valves
• Reduced noise and vibration during closure
• Better performance at low pressures
• Improved sealing reliability in water systems

Applications

Water distribution systems, heating installations, HVAC systems, booster sets, plantrooms, irrigation systems, and general mechanical pipework where reliable one-way flow control is required.
