B6 50 PREMIUM ACS SWING CHECK VALVE WORKING PRESSURE 16 BAR - WITH COUNTERWEIGHT
Check Valve is designed to protect your pumps and network against flow inversion. BELGICAST provides a wide range of check valves to meet the many factors that determine the choice of a design.
These selection factors can lead you to choose the oldest and most common type: the swing check valve. For drinking or filtered water, BELGICAST Swing Check Valves are designed to provide a reliable, easy and long-lasting solution.

Features
- RELIABLE WATER TIGHTNESS - Spherical trunnion to provide a self-centring effect of the valve disc in the body seat
- ROBUST DESIGN - Corrosion-proof internal components for a long lifetime. Lubricated bearings for guiding of the turning shaft and low friction
- EASY MAINTENANCE - Complete dismantling of the bonnet and closing sub-assembly due to the shaft located in the bonnet
- Low head loss and opening on low differential of pressure – Provided by an efficient design. The body and bonnet contribute to a 93% free passage of the fluid. The internal sub-assembly is also optimized to achieve a prompt reaction of the check valve opening. Finally lubricated bearings in copper alloy bring, at the same time, a perfect guidance of the turning shaft and a low coefficient of friction.
- Stainless steel internal parts (shaft, seat, clapper arm and flap) ensure a long service life and lower operational costs. In addition, the clapper arm is equipped with damping buffers in rubber to limit the noise and impacts while full opening.
- Removable bonnet and internal parts for easy maintenance, without removing the check valve from the pipe. The bonnet holding the complete internal sub-assembly can be dismantled from the body for direct and simple access to various components (Except for DN 350 and DN 400)
- With counter-weight – Counter-weight is on left bank in standard configuration
- Horizontal or upward vertical installation are possible
- PERFECT SELF-CENTRING - The ball-shaped trunnions enable self-centring of the valve disc in the housing seat, which results in a permanently adaptable seal.
- This ensures a precise and fault-free operation of the non-return valve, even in case of low back pressure.
- IDEAL OPENING ANGLE - The 93% opening value guarantees an extremely low zeta value (coefficient of resistance), a head loss of less than eight m bar in the fully openened position and therefore enables economic operation of the valve.
