Flow Control

Valve duty before valve colour.

Isolation, regulation, non-return and control valves selected by service, material, pressure, temperature, end connection and required approval.

Visual product guideEvery valve family, clearly separated

Gate, ball, butterfly, check, globe, control valves and strainers each have their own complete image, size range and application.

Authentic Product Finishes

Function is specified—colour is manufacturer-led.

Blue epoxy is familiar on many ductile-iron water valves; red commonly appears in fire-service products; brass, stainless, steel and black-painted finishes vary by construction and brand. Colour never replaces a datasheet.

Indicative Supply Guide

Types, connections & ratings.

Valve ranges vary more by model than by family. Confirm body, trim, seat, pressure-temperature rating and shut-off requirement.

Colour note: The website does not assign service solely by body colour. The selected product must be verified from the manufacturer’s datasheet and project approval.

Valve and strainer coverage

Product	Indicative size range	Common configurations
Gate valve	½–24 in typical; larger steel models by enquiry	Threaded, socket-weld, flanged or grooved
Ball valve	¼–12 in by design	Threaded, socket-weld, butt-weld or flanged
Butterfly valve	2–24 in typical; larger by model	Wafer, lug, flanged or grooved
Globe / balancing valve	½–12 in by construction	Threaded or flanged; regulating or isolation
Check / foot valve	½–24 in by type	Swing, dual plate, silent, threaded, flanged or grooved
Diaphragm / needle / solenoid	Model- and service-dependent	Threaded, flanged or manufacturer-specific connection
Y / basket strainer	½–24 in by type	Threaded, flanged or grooved

Pressure and end connection

System	Typical designation	Confirm
Iron water-service valves	PN10 / PN16 or Class 125 / 150	Flange drilling, pressure-temperature rating
Steel valves	ASME Class 150–2500 by design	Body/trim material and applicable valve standard
Threaded valves	Manufacturer WOG / pressure rating	Thread standard, seat and temperature
Grooved valves	System working-pressure rating	Groove profile, approval and gasket compound
Fire-service products	UL/FM where project requires	Exact listed/approved model and accessories
