What are the standards for plastic check valves and plastic gate valves? ?
Plastic valves – International standards. Material requirements: The materials used for the valve body, valve caps, and gland covers must meet the specifications outlined in ISO 15493:2003 \"Plastic piping systems for industrial use – ABS, PVC-U, and PVC-C – Specifications for pipe and fitting systems – Part 1: Metric series\" and ISO 15494:2003 \"Plastic piping systems for industrial use – PB, PE, and PP – Specifications for pipe and fitting systems – Part 1: Metric series\". **Standards: \"Thermoplastic Plastic Globe Valves\", \"Thermoplastic Plastic Butterfly Valves\", \"Metric Series of Basic Dimensions for Polypropylene (PP) Valves Used in Pressure Pipelines\", \"Pressure Testing Methods and Requirements for Thermoplastic Plastic Valves\", \"Plastic Manifolds\", and \"Rigid Polyvinyl Chloride (PVC-U) Valves for Water Supply\"
EN ISO 16139-2007 Industrial valves – Gate valves made of thermoplastic materials. EN ISO 16137-2006 Industrial valves – Check valves made of thermoplastic materials
Are there standards for other types of plastic ball valves, diaphragm valves, gate valves, etc.? ?
