Product catalog summary
Specifications:
The document details angle seat or right angle piston valves available in sizes ranging from 1/2" to 2" with a pressure rating of PN16. The valves have pipe threads conforming to ISO228 standards and are available in Normally Closed (NC), Normally Open (NO), and Double Action (DA) versions. They support unidirectional flow from 1 to 2 and operate within an ambient temperature range of -20°C to +60°C. The pilot pressure required ranges from a minimum of 4.0 bar to a maximum of 8.0 bar.
Materials:
The valve body and seal holder are made of brass, while the piston is constructed from aluminum. The cylinder is made from heat-stabilized PA66 nylon, and the piston rod is stainless steel AISI 304. Internal o-rings and shutter seals are made of FKM, with optional PTFE or EPDM seals available upon request.
Performance:
The valves are designed for fluid control up to +80°C. The datasheet provides detailed specifications for various models, including maximum differential pressure (ΔP Max) and flow coefficient (Kv) values for different sizes and configurations.
Technical Data:
The document includes tables listing the codes, gas pipe thread sizes, nominal diameters (DN), maximum lengths, cylinder diameters, and performance metrics such as ΔP Max and Kv for each valve model. The flow coefficient Kv indicates the volume flow rate of water through the valve under specified conditions (ΔP = 1 bar, T = 5-40°C, density = 1000 kg/m³).
