Beyond standard products, we specialize in custom selection and system integration according to your medium, pressure, temperature, and control requirements.


World-Class Manufacturing Strength - Precision Defines Quality

As an ISO9001 certified company, KINKO-FLUID follows international standards in both hardware and software:

Automated assembly line - imported advanced assembly lines for modular and batch production of actuators and valves, ensuring excellent consistency.

Precision CNC machining - high-accuracy CNC machining centers holding tolerances as tight as ±0.01 mm for critical components (pistons, gear shafts, stems).

Complete testing equipment - material spectrometers, CMM, pressure test benches, leak testers, cycle life testers, etc. Every product undergoes:

Shell strength test (1.5 × rated pressure)

Low-pressure sealing test (0.6 MPa air)

Cycle life test (over 100, 000 cycles under simulated conditions)

We produce and test according to ISO, DIN, 3A, IDF, SYS, JIS and GB standards. For sanitary/hygienic applications, our products fully comply with FDA and GMP requirements, making them ideal for food, beverage, biopharma, and sterile filling lines.


Core Product Advantages - Why Choose KINKO-FLUID?

 Pneumatic Actuator - Compact, Efficient, Long-Life

Die-cast aluminum alloy cylinder with hard anodized surface - corrosion and wear resistant.

Double piston rack-and-pinion design - stable torque output, opening/closing in 0.2~0.5 seconds.

NAMUR standard solenoid valve interface - easy mounting of limit switches or positioners.

Operating temperature: -20°C to +80°C (high-temperature version up to +200°C).

 Electric Actuator - Intelligent, Precise, Energy-Saving

Integrated control module supports 4-20mA / 0-10V analog control, on/off, modulating, and bus communication (Modbus / Profibus).

Triple protection: Over-torque, over-heat, phase loss.

IP67 rating (IP68 submersible optional) - suitable for outdoor, humid, dusty environments.

Butterfly Valves & Ball Valves - Zero Leakage for Demanding Conditions

Butterfly valves: Soft-seated (concentric) or hard-seated (eccentric), sizes DN50~DN1200, for water, oil, gas, mild acids/bases.

Ball valves: Floating or trunnion design, full bore, fire-safe option available. Suitable for steam, natural gas, high-viscosity media.

Sealing materials: PTFE, RPTFE, PPL, metal-to-metal - for corrosive, high-temperature, or abrasive media.

 Pneumatic Angle Seat Valve - Fast Operation, Hygienic Grade

316L stainless steel body, mirror polished internally (Ra ≤ 0.4 μm), no dead corners, compatible with CIP/SIP cleaning.

Low water hammer effect, service life exceeding 2 million cycles. Widely used in filling machines, fermentation tanks, batching lines.

 Control Valves - Precise Regulation of Process Parameters

Electric/pneumatic single-seat or cage control valves with compact positioner - control accuracy ±0.5% FS.

Suitable for temperatures from -196°C to +450°C and pressures PN16 to PN160.
