Cooling Water System
View system integration details
This page explains how Control Valves & Piping is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
Control valves and piping form the distribution network within cooling water systems, responsible for regulating flow rates, directing water to specific equipment, and maintaining proper pressure levels throughout the system to ensure efficient heat transfer and temperature control.

Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The reference range is 1.0–1.6 MPa. Always confirm the exact rating for your specific model and application with the manufacturer.
Body materials include WCB (carbon steel), CF8, and CF8M (stainless steel) per ASTM A216/A351. Seat materials are typically PTFE or PPL per ASTM D3294. Material selection depends on fluid compatibility, temperature, and pressure requirements.
Nominal diameter (DN) ranges from DN15 to DN300 per ISO 6708. Selection is based on required flow rate and pipe size. Consult engineering guidelines and verify with the manufacturer to ensure proper sizing for your cooling water system.
Leakage rate is specified as 0.01–0.05% of rated flow per IEC 60534-4, corresponding to Class IV–VI. This indicates the allowable internal leakage when the valve is closed. Lower leakage classes are required for applications demanding tight shut-off.
