German transmission developments valves, transmission developments models, transmission developments prices

transmission developments valves, also known as pinch valves, tube squeeze valves, bladder valves, and shut-off valves. They use pneumatic, electric, manual, or hydraulic actuation to squeeze 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 of a pinch valve, providing corrosion resistance, wear resistance, and pressure-bearing capacity. Additionally, the quality of internal components such as the solenoid coil, armature, and spring affects the valve's service life. It is driven by an electromagnetic solenoid to control on/off status by squeezing or releasing the hose. The medium flows only through the hose, and other parts of the valve body do not come into contact with the medium. This means that, compared to other types of solenoid valves, pinch valves can handle media with particles without clogging.

transmission developments 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 tubing, making it relatively economical.

transmission developments valve installation

Silicone hose (inner wall is very smooth, excellent memory; the tube will not stick even after long periods in the closed state). Biochemical hose (resistant to acid, alkali, and solvent environments, but not recommended for use in oily or organic solvents). The hose installation slot on the valve body has a smooth arc structure, allowing users to easily install and remove the hose. 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.

transmission developments 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, it should be tightened promptly to prevent wear at the connection or loss of the handwheel and nameplate. If the handwheel is lost, it must not be replaced with an adjustable wrench; it should be replaced promptly. The packing gland must not be skewed or lack pre-tightening clearance. For valves in environments prone to contamination by rain, snow, dust, and sand, protective covers should be installed on the valve stems. Scales on valves 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 not permitted; this is strictly prohibited for non-metallic valves and cast iron valves in particular.
