District heating pipes - Preinsulated bonded pipe systems for directly buried hot water networks - Steel valve assembly for steel service pipes, polyurethane thermal insulation and outer casing of polyethylene

This European Standard specifies requirements and test methods for valves of prefabricated thermally insulated valve assemblies comprising a steel valve, rigid polyurethane foam insulation and an outer casing of polyethylene for use in directly buried hot water networks with pre-insulated pipe assemblies in accordance with EN 253. This standard applies only to insulated valve assemblies for continuous operation with hot water at various temperatures in accordance with EN 253, Clause 1 and the valve assemblies with a maximum operation pressure of 25 bar. For higher pressures additional demands apply. Guidelines for quality inspection are given in Annex A of this standard. NOTE   For this application the following valve types are commonly used: ball valves, gate valves, and butterfly valves. This standard does not include calculation rules for loads and stresses. These depend on the configuration of the system as it is installed. The design and installation rules are given in EN 13941.

This document specifies a test method for the determination of the opening, closing and running torque of thermoplastics valves.
This document is applicable to all types of manually operable thermoplastics valves, with or without actuator, intended to be used for the transport of fluids.
NOTE 1        Examples of valve types tested with this method are in ISO 4437-4, ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 16486-4, ISO 21787, EN 1555-4[13] and EN 12201-4 [14].
This document does not specify the relationship between the torque and its possible increase after prolonged use of the valve under a specific working condition or wear/chemical aggression of the materials.
NOTE 2        Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358 concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closing operations.

Plastics piping systems for water supply, and for drains and sewers under pressure - Polyethylene (PE) - Part 4: Valves for water supply systems
SIST EN 12201-4:2024

This document specifies the characteristics of valves or valve bodies made from polyethylene (PE) for buried and above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drains and sewers under pressure, vacuum sewer systems, and water for other purposes, with the exception of industrial applications.
NOTE 1   For PE components intended for the conveyance of water for human consumption and raw water prior to treatment, attention is drawn to 6.4. Components manufactured for water for other purposes, drains and sewers, and vacuum systems are possibly not suitable for water supply for human consumption.
NOTE 2   Industrial application is covered by EN ISO 15494 [2].
The intended use includes sea outfalls, laid in water and pipes suspended below bridges.
It is applicable to isolating unidirectional and bi-directional valves with spigot ends or electrofusion sockets intended to be fused with PE pipes or fittings conforming to EN 12201-2 and EN 12201-3 respectively.
Valves made from materials other than PE, conforming to the relevant standards can be used in PE piping systems according to EN 12201, provided that they have PE connections for butt fusion or electrofusion ends, conforming to EN 12201-3, or material transition joints (e.g. flanged joints).
NOTE 3   For valves or valve bodies intended for drains and sewers, additional information is given in Clause 9.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with EN 12201-1, EN 12201 2, EN 12201 3 and EN 12201 5, this document is applicable to PE pipes, fittings and valves, their joints and joints with components of PE and other materials intended to be used under the following conditions:
a)   allowable operating pressure, PFA, up to 25 bar ;
b)   an operating temperature of 20 °C as a reference temperature.
NOTE 4   For applications operating at constant temperature greater than 20 °C and up to 50 °C, see EN 12201-1:2024, Annex A.
The EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours and additives.
NOTE 5   It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
This document covers valves for pipes with a nominal outside diameter dn ≤ 400 mm.
