DIAMANT 2000 brass ball valve

DIAMANT 2000 brass ball valve

Product catalog summary

Specifications:
The document details the specifications of brass ball valves used in various systems such as HVAC, drinking water, and alternative energy systems. The valves are compliant with Ministerial Decree 174 and are made from brass (CW 617N) with nickel plating, PTFE seals, and EPDM O-rings. They are designed for full bore connections and can handle fluids like water with up to 30% glycol, operating within a temperature range of +5°C to +110°C.

Technical Features:
The valves are available in 2-way and 3-way configurations, with different KvS values indicating flow capacity. The 3-way valves have a unique feature allowing them to mix or divert flow by rotating a 3-hole sphere. The 2-way valves can be mounted in any flow direction.

Installation Guidelines:
Valves should be installed with the actuator connection not facing downwards. High-pressure water should not be used directly on the actuator. The document provides dimensions for proper installation and connection to the actuator.

Materials Used:
The valves are constructed from brass with nickel plating, and components include PTFE sleeves and seals, and EPDM and NBR O-rings. The document specifies the materials for each part of the valve.

Hydraulic Versions and Features:
The document lists various models with their respective DN, PN, connections, and KvS values. It also describes the operation of diverter and mixer valves, including the unique features of by-pass valves.

Certifications:
The company is UNI EN ISO 9001:2015 certified, ensuring quality management standards are met.

Additional Information:
