Wholesale Industrial Valve Suppliers
Source ball valves, butterfly valves, gate valves, globe valves, check valves, control valves, and solenoid valves from verified manufacturers on Towobo. Industrial valves are the flow control and isolation devices of every process plant — oil and gas, chemical, power generation, water treatment, food and beverage, and HVAC. Italy dominates premium process valves (Velan, Emerson Fisher Italy); Germany leads in industrial automation valves (Festo, SMC Germany); China is a major source for cost-competitive general-purpose and export-grade valves.

Industrial valves are classified by their operating mechanism and application: ball valves — a spherical ball with a bore controls flow by rotating 90° between open and closed positions; full bore or reduced bore; rising or non-rising stem; manual, pneumatic, or electric actuation; used for isolation in gas, oil, water, and chemical services; rated to ANSI Class 150–2500 or PN10–PN400 pressure classes; butterfly valves — a disc rotates 90° in the flow path; compact and lightweight; concentric, double-eccentric (high-performance), or triple-eccentric (metal seat) designs; used for large-diameter isolation and flow control in water, HVAC, and process piping; gate valves — wedge gate moves perpendicular to flow to open/close; rising or non-rising stem; low pressure drop when fully open; used for isolation in piping systems where infrequent operation is expected; globe valves — globe-shaped body with plug or disc for throttling and flow control; suitable for frequent operation; used where flow regulation is needed; check valves — prevent reverse flow — swing check, lift check, dual-plate wafer check types; control valves — modulating valves actuated by pneumatic (4–20mA), electric, or hydraulic signal to regulate flow, pressure, temperature, or level — Emerson Fisher, Flowserve, Samson (Germany) are the leading brands; solenoid valves — two-way or three-way electrically operated pilot valves for pneumatic or hydraulic circuits; Festo, Parker, ASCO, and Bürkert are key manufacturers. Key standards: API 6D (pipeline valves — full bore ball and gate valves); API 608 (metallic ball valves); API 600/6FA (fire-safe design for ball, gate, globe, and check valves); BS 6755 / ISO 10497 (fire testing of quarter-turn and check valves); ASME B16.34 (valves for pressure-temperature ratings); PED (Pressure Equipment Directive, 2014/68/EU — required for valves on European process equipment above minimum size/pressure thresholds).
