Every family below is manufactured or assembled and tested at our Ningbo factory. Series codes follow the printed Kailing catalog — quote them directly in your RFQ.

Direct-acting and pilot-operated 2/2, 3/2 and 5/2 valves in brass and stainless bodies for air, water and light oils. The 2WB series carries an IP67 national test report; CE EMC verification covers the main solenoid lines. AC and DC coil voltages available.

Pneumatically piloted piston valves in stainless steel for steam, hot water and aggressive media — high cycle life where solenoid valves struggle. Y-type variants with manual flow adjustment available.

Standard ISO, mini, compact and twin-rod guided cylinders with magnetic pistons and adjustable cushioning. Bore, stroke and mounting combinations built to order alongside stocked standards.

AT-series rack & pinion quarter-turn actuators, double-acting and spring-return, for ball and butterfly valve automation. NAMUR interfaces for direct solenoid and limit-switch mounting.

KLST-series precision electric actuators for quarter-turn ball and butterfly valve automation — on/off (B), position-feedback (R), intelligent modulating (A) and non-contact (S) types, with manual override and a range of supply voltages.

Two- and three-piece stainless ball valves delivered as complete actuated packages — threaded, flanged or tri-clamp ends, with pneumatic or electric actuators, assembled and leak-tested in-house.

Wafer-type butterfly valves paired with AT actuators for water treatment, dust collection and general process shut-off. Limit switch boxes and solenoid pilots fitted on request.

Filter-regulator-lubricator combinations and individual units that protect every component downstream. Two-unit and three-unit combinations across five frame sizes with gauges and auto drains.

Right-angle and submerged pulse jet valves for baghouse dust collector cleaning — fast-opening diaphragms for a sharp cleaning pulse and long service life.

Hand-lever, foot-pedal and roller-operated valves, plus one-way flow controls and check valves, for operator stations and machine sequencing where electrical control is unnecessary or undesirable.

One-touch push-in fittings, speed controllers, function fittings and adapters in metric and BSP threads — the consumables every panel builder reorders.

PU, PA and PF tubing in straight lengths and self-recoiling coils, in standard colors and metric sizes, matched to our push-in fitting range.

GT-series pneumatic turbine vibrators and air hammers that keep hoppers, chutes and screens flowing — quiet, oil-free operation with adjustable force via air pressure.

Seal kits, rod clevises, floating joints, mounting brackets and magnetic switches — keep installed cylinders serviceable for years after purchase.
Include medium, pressure, port size and voltage — we confirm specification and price, usually within one working day.
