Shut-Off-Valves CNA 50

Product catalog summary
Overview: The document outlines the specifications and applications of LOHSE COMPACT-gate valves, specifically the CNA type, used across industries such as paper, chemical, food, and biogas. These valves are designed for shutting off stock and aggressive media.
Applications: These valves are ideal for pulp and paper production, chemical industry, food industry, water and wastewater management, and biogas plants, noted for their corrosion resistance and ability to handle viscous and aggressive media.
Construction and Materials: Constructed entirely of stainless steel, these valves ensure corrosion and acid resistance. Key components include a valve plate, stuffing box gland, and housing plate. Seals are available in EPDM, VITON, or NBR, and the valves are designed to be 100% water-tight.
Specifications: The document details dimensions, materials, and pressure ratings for valve sizes ranging from DN 50 to DN 1200. Maximum operating pressure varies from 8 bar for smaller diameters to 1.5 bar for the largest. Operating temperature depends on the seal type, with NBR seals rated up to 105°C and EPDM up to 120°C.
Modular System: LOHSE valves feature a modular system for interchangeable operating elements, simplifying maintenance and reducing spare parts inventory. This system also allows easy replacement of actuating elements and valve drives.
Standards and Testing: The valves comply with DIN EN 12266-02:2012-04 for leak testing and are designed according to DIN EN 1092-1 and ANSI standards for flange dimensions.
Additional Features: The document includes tables of dimensions and weights for various valve configurations, including handwheel, pneumatic, and electric drives. It also outlines the use of protection guards as per machinery directive 2006/42/EG.
Specifications: Specifications for COMPACT-valve with a square head are provided, detailing dimensions and weights for sizes DN 50 to DN 600. The pressure rating is 8 bar for most sizes, with larger sizes having lower ratings.
Procedures and Standards: Valves comply with ANSI B 16.47 Class 150 standards for sizes DN 700 and above, with further sizes available upon request.
Contact Information: Contact details for distributors and agencies across various countries are listed, including Germany, Australia, New Zealand, and many others.
Key Observations: The document provides a comprehensive list of international contacts for distribution and support, detailed valve specifications covering a wide range of sizes and dimensions, and emphasizes compliance with international standards for larger valve sizes.

Applications Paper industry and chemical industry pulp and paper production LOHSE COMPACT-gate valves have proved their value and reliability in all branches of ins paper and chemical industries. CNA-valves are “shut-off” type valves. The type is suitable for shut-off of stock and aggressive media. chemical industry Industrial sewage treatment water wastewater When LOHSE COMPACT-gate valves of acid resistant stainless steel are installed in waste water treatment plants, the need to use expensive isolation appliances to guard against contact-corrosion is removed.

Operating elements – the LOHSE modular system All LOHSE COMPACT-valves comprise the following main groups: • valve body type: CNA • operating elements type Hns, H, P, PV, E, GK, K, X All elements are interchangeable for any given size. Thereby the connections of brackets as well as the coupling of actuator and valve plate will be removed and fixed again after the exchange. No removal of incorporated valve body (notice safety rules – pipes must be pressureless). This facility is called the LOHSE modular system which offers the following advantages: • simplified and less expensive holding of spare...
