Filling valve design
For filling in two stages: COARSE-FINE. The design is based on a hemisphere that offers little resistance to the product flow. The product-conducting inner walls have a smooth surface and are clearly visible from the outside. The valve neck features a centring groove for easy positioning in the valve receptacle. The valve tappet forms the connection to the valve cylinder. It does not come into contact with the product. A pressure spring closes the valve securely in the event of mains or air failure. In the standard version, the valve plug opens outwards.
Filling types: professional filling
Above-surface Filling
Above-surface / below-bunghole filling
Partial below-surface filling
Below-surface filling
Partial below-surface filling
- Open containers or containers with bunghole
- Slightly foamy product
- First, the product is filled above the surface; as the product level rises, the filling nozzle dips into the product (below-surface filling)
- Suitable for below-bunghole-above-surface dosing
- Nominal sizes from NW14 to NW54
- Filling nozzle length 365 mm
Below-surface filling
- Open containers or containers with bunghole
- Foamy product or product with static charge in explosive environment
- The filling nozzle is lowered to just above the bottom of the container
- Filling starts immediately with below-surface filling
Below-surface filling valve 903
- Suitable for below-bunghole-below-surface dosing
- Nominal sizes from NW14 to NW54
- Filling nozzle length 565 or 1165 mm
- Bellows seal
- Valve opens inwards
- Straight product flow without lateral scattering
- Product flow reduced by approx. 30%
- Heating jacket
- Bypass arrangement
- Heating jacket for bypass
- Polished inside (food-safe)
- Parallel inlet
- Connection flange
- Stainless steel valve V2A-4541, V4A-4571
- Polypropylene plastic valve with Teflon bellows seal
- Valve seal steel to steel or stainless steel to stainless steel
- Three-stage valve design: COARSE-FINE-FINEST
- Proximity switches for signalling valve position
- Solenoid valves and proximity switches in ex design
