German Bifold valve Bifold model Bifold price

Bifold valves, also known as pinch valves, tube squeeze valves, bladder valves, and cuff valves, use pneumatic, electric, manual, or hydraulic actuation to compress the sleeve for on/off or regulation functions. Solenoid pinch valves are a type of pinch valve. The sleeve (hose) is the most critical component, providing corrosion resistance, wear resistance, and pressure-bearing capacity. The quality of internal components such as the solenoid coil, armature, and spring also affects valve life. Driven by a solenoid, it controls flow by compressing or releasing the hose. The medium flows only through the hose, and other parts of the valve body do not contact the medium, meaning that compared to other types of solenoid valves, pinch valves can handle media with particles without clogging.

Bifold valve features

1) The voltage range is the widest among imported products, allowing a fluctuation range of ±5%. 2) Wide application range, suitable for most microfluidic fields. 3) Low power consumption and good heat dissipation efficiency. 4) Dedicated matching hoses ensure optimal rebound life. 5) Stable product performance and quality. 6) Maintenance requires only replacing the hose assembly, making it relatively economical.

Bifold valve installation

Silicone tubing (inner wall is very smooth, excellent memory; the tube will not stick even after long periods in the closed state). Biochemical tubing (resistant to acid, alkali, and solvent media, but not recommended for use with oily or organic solvents). The hose installation slot on the valve body has a smooth arc structure, allowing users to easily install and remove hoses. The gap in the hose installation slot is slightly smaller than the outer diameter of the hose, ensuring the hose is tightly fixed during operation.

Bifold valve usage precautions

For valves in operation, all valve components should be complete and intact. Bolts on flanges and supports must not be missing; threads should be undamaged, and loosening is not permitted. If the locking nut on the handwheel is found loose, tighten it promptly to prevent wear at the connection or loss of the handwheel and nameplate. If the handwheel is lost, do not substitute with an adjustable wrench; replace it promptly. The packing gland must not be skewed or lack pre-tightening clearance. For valves in environments prone to contamination by rain, snow, dust, sand, etc., install a protective cover on the valve stem. Scales on the valve should remain complete, accurate, and clear. Lead seals, caps, pneumatic accessories, etc., should be complete and intact. Insulation jackets should have no dents or cracks. Striking, standing on, or supporting heavy loads on operating valves is prohibited; this is especially strictly prohibited for non-metallic and cast iron valves.
