The size of a STORZ coupling can be verified by measuring the distance between lugs (measured on the inside). Distance between the lugs: 31 mm, 44 mm, 51 mm, 66 mm, 81 mm, 89 mm, 105 mm, 115 mm, 133 mm, 148 mm, 160 mm, 188 mm, 220 mm, 278 mm. The most popular sizes: [...]
STORZ couplings are couplings designed for fluid and bulk transfer systems. They are used in firefighting, irrigation systems, chemical industry, food industry, agriculture, etc. The couplings feature symmetrical locking heads (no male/female difference) Therefore, they can be easily connected by turning them by 22°, either manually or with a spanner. It is important to connect [...]
A plastic hose contains plasticizers to maintain its flexibility. The type of plasticizers used depends on the hose's intended purpose and its compatibility with specific simulants (as per Regulation 10/2011/EU). Certain substances transported through the hose can leach out some plasticizers, causing the hose to become rigid over time. This typically occurs when the hose [...]
Not every food-grade hose is suitable for all types of food. Each food substance can be assigned to specific types of food and simulated during migration testing using a specific simulant, as outlined in the detailed table of Regulation 10/2011/EU (for example: milk and alcohol with 20-50% content require liquid D1, vinegar – liquid B, [...]
Drinking water (water intended for human consumption) is subject to specific regulations. Drinking water, along with its transmission and distribution installations (including hoses used for this purpose), is governed by general European regulations (Directive 98/83/EC) as well as specific national regulations: PZH - National Institute of Public Health – National Hygiene Institute (Poland), KTW - [...]
There are numerous standards for food-grade hoses. The requirements for hoses approved for use within the European Union are outlined in legal regulations: Regulation 1935/2004/EC, Regulation 2023/2006/EC, Regulation 10/2011/EU. Customers often require compliance with other standards, such as: FDA – Food and Drug Administration, NSF – National Sanitation Foundation, 3-A – 3-A Sanitary Standards, BfR [...]
The location of pressure gauge connection can be: - bottom (radial), – centric back , – eccentric back.
Pressure gauges come in the following sizes: 40, 50, 63, 80, 100, 160 and 250.
The accuracy class indicates the limits of permissible error and is expressed as a percentage of the full-scale range. There are the following accuracy classes: 0.1%, 0.25%, 0.6%, 0.5%, 1%, 1.6%, 2.5% and 4%.
The optimum measuring range of a pressure gauge is when the operating pressure is confined to 25% and 75% of the scale.
