Sanitary Stainless Steel Valves, Fittings & Pumps

Henan Zhonglian Machinery Equipment provides a complete portfolio of food-grade and sanitary-grade stainless steel fluid handling components, covering sanitary valves, pipe fittings and sanitary pumps. All products are manufactured from premium 304 and 316L stainless steel, with fine surface finishing and stable working performance. As core supporting components for sanitary fluid delivery systems, they are fully compatible with food processing, filtration, filling and packaging production lines, and widely used for new line construction, existing line renovation and routine maintenance.

Sanitary Valves

We offer a full range of sanitary valves to satisfy on-off control, flow regulation, non-return protection and sampling demands in fluid pipelines. All valves feature smooth internal flow channels with no sanitary dead corners, ensuring smooth material delivery and convenient cleaning & sterilization, and fully comply with hygiene standards of food and pharmaceutical production. They are available in manual, pneumatic and solenoid actuated configurations to match different automation levels.

Manual Valves

Our manual valve portfolio includes sanitary butterfly valves, ball valves, check valves, diaphragm valves and sampling valves. Operated manually with a handle or handwheel, they feature simple structure, reliable sealing and cost-effective performance, and are ideal for conventional pipeline on-off control, flow adjustment and process isolation. They are the most widely used valve type for small and medium-sized food production lines.

Pneumatic Valves

Driven by pneumatic actuators, pneumatic sanitary valves are designed for automated production lines. They support remote control and fast switching, and feature explosion-proof performance, making them suitable for high-frequency operation and hazardous working environments. With the same sanitary internal structure as manual valves, they are fully compatible with CIP and SIP cleaning processes, and are an essential component for fully automated sanitary production systems.

Solenoid Valves

Solenoid sanitary valves are electrically controlled for precise and fast on-off response. They are compact in size and can be easily integrated into automatic control systems, suitable for fluid circuits that require precise timing control and rapid switching. They are widely used in dosing, filling and automatic cleaning systems to achieve accurate fluid control.

All valves are available in threaded, welded, clamp quick-fit and flanged connection types, and can be manufactured in accordance with ISO, DIN, DF, SMS, 3A and other international industrial standards.

Sanitary Pipe Fittings & Tubing

Our fitting and tubing series covers all commonly used sanitary pipeline connection parts and tubing products, forming a complete piping solution matched with our sanitary valves and pumps.

Pipe Fittings

The product range includes sanitary elbows, equal and reducing tees, concentric and eccentric reducers, quick-fit clamp couplings and round thread unions. All products are precision machined with smooth internal and external surfaces, ensuring reliable sealing and no material residue. We also accept custom fabrication of non-standard stainless steel fittings according to customer drawings and on-site process requirements.

Sanitary Stainless Steel Tubing

We supply sanitary stainless steel mirror-polished tubes in both thin-wall and thick-wall specifications, made of 304 or 316L stainless steel with uniform wall thickness and excellent surface finish. The tubes are suitable for all sanitary fluid delivery pipelines, and can be cut and customized according to actual project requirements.

Four connection methods are available for the whole fitting series: threaded connection for pipelines requiring frequent manual disassembly; welded connection for permanent installation with high sealing and pressure resistance; clamp quick-fit connection, the most widely used sanitary solution for fast disassembly and thorough cleaning; and flanged connection for high-pressure, large-diameter pipeline systems with reliable connection strength.

Sanitary Pumps Series

We provide a full line of sanitary pumps for different material properties and process requirements, all constructed with food-grade stainless steel wetted parts and designed for easy cleaning and maintenance. They are ideal power units for material conveying, filtration, cleaning and filling processes in food and beverage production.

Sanitary Product Pump (Centrifugal Pump)

Specially designed for high-concentration slurry and viscous materials, the thick slurry pump features a wide flow channel that is not easy to clog. It delivers stable and reliable conveying performance, and is widely used in production lines for jam, syrup, thick sauce and other high-viscosity products.

Sanitary Screw Pump

As a single-screw positive displacement pump, it delivers extremely smooth and pulsation-free conveying with stable flow rate. It is suitable for high-viscosity and shear-sensitive materials, and is an ideal choice for precision conveying of sensitive food and pharmaceutical products.

Sanitary Lobe Pump (Rotor Pump)

As a positive displacement pump, the lobe pump delivers gentle and pulsation-free conveying. It is ideal for high-viscosity materials and products containing particles, and will not damage the material structure and texture. It is widely used for conveying sauces, pastes, concentrates and other viscous food materials.

Pneumatic Diaphragm Pump

Powered by compressed air with no need for power supply, the diaphragm pump has strong self-priming capacity and can handle materials containing particles. It features explosion-proof performance and flexible mobility, and is suitable for mobile filtration units, material transfer and working scenarios without power access.

Self-priming Sanitary Pump

Featuring strong self-priming capacity, this pump can start up without pre-filling the pump chamber. It is suitable for conveying low to medium viscosity liquid materials, and is widely used for raw material transfer and CIP cleaning liquid circulation in food production lines.

Sanitary Product Pump (Centrifugal Pump)

As the most widely used general-purpose sanitary pump, the centrifugal product pump delivers stable and smooth flow with low shear force. It has a simple and compact structure with easy disassembly and cleaning, and is the standard choice for conveying various liquid food materials such as beverages, fruit juice and dairy products.

Return Pump

Specially designed for CIP return and residual material recovery, the return pump is equipped with a dual-inlet structure to efficiently recover residual liquid from pipelines and equipment. It helps reduce material waste and improve cleaning effect, and is an essential supporting pump for cleaning systems.

Constant Pressure Variable Frequency Pump

Integrated with a variable frequency control system and pressure tank, this pump delivers stable constant pressure output. The pressure can be adjusted flexibly according to process demands, with energy-saving performance. It is especially suitable for filling, spraying and other processes that require high pressure stability.

Standards & Craftsmanship

All our valves, fittings and pumps come in a wide variety of specifications, with exquisite polished appearance and stable working performance. Products can be manufactured in full compliance with ISO, DIN, DF, SMS, 3A and other international industrial standards. We also provide flexible customization options in terms of surface finish, material grade and connection type, to precisely match the specific requirements of different industries and working conditions.

Application Industries

With reliable sanitary performance and consistent quality, our stainless steel valves, fittings and pumps are widely used in food, pharmaceutical, dairy, brewery, beverage, fine chemical and other industries requiring hygienic fluid handling. All technical indicators have reached international advanced level, and can fully meet the strict hygiene and safety requirements of high-standard production lines.
