Provides material requirements and performance tests for metallic-bodied hydraulically operated automatic control valves for waterworks purposes, together with default compliance requirements for use by manufacturers and certification bodies.

Scope

This Standard specifies requirements for metallic-bodied PN 16, PN 21 and PN 35 hydraulically operated, diaphragm or piston-actuated, globe or piston-style, automatic control valves for waterworks purposes and valve sizes DN 40 to DN 900 (inclusive), suitable for, but not limited to, drinking water and recycled water, with a maximum operating temperature of 40°C.
This Standard applies to automatic control valves that operate by pressure in water mains, and controlled by hydraulic or solenoid pilot valves. Where control valves incorporate solenoid pilots, limit switches or position transmitters, low-voltage electrical power supply is required for these components.
This Standard covers the following types of automatic control valves:
(a) Fixed-outlet pressure-reducing valve.
(b) Variable-outlet pressure-reducing valve.
(c) Pressure-sustaining/relief valve.
(d) Surge-anticipating valve.
(e) Altitude valve.
(f) Float valve.
(g) Rate-of-flow control valve.
(h) Non-return valve.
)i) Solenoid-control valve.
The valves are designed for installation in a horizontal or vertical position depending on the manufacturer’s requirements, above-ground or below-ground in a drained chamber.
NOTE: Purchasing guidelines are given in Appendix B.
