German Hydropa valves Hydropa models Hydropa prices

Hydropa valves serve an on/off function. They are commonly installed at the inlets and outlets of cold and heat sources, at equipment inlets and outlets, and on pipeline branches (including risers); they can also be used as drain valves and air vent valves. Common shut-off valves include gate valves, globe valves, ball valves, and butterfly valves. Gate valves can be classified as rising-stem or non-rising-stem, single-disc or double-disc, and wedge-gate or parallel-gate. Gate valves do not provide tight shutoff, and large-diameter gate valves are difficult to open; the valve body size along the flow direction is small, resulting in low flow resistance, and gate valves cover a wide range of nominal diameters. Globe valves are classified by media flow direction into three types: straight-through, angle, and Y-pattern, and are available in rising-stem and non-rising-stem versions. Globe valves provide better shutoff tightness than gate valves, have longer valve bodies, higher flow resistance, and a maximum nominal diameter of DN200. The ball valve core is a perforated sphere. When the valve stem is actuated so that the bore in the sphere aligns with the pipeline axis, the valve is fully open; rotating it by 90° results in full closure. Ball valves offer some throttling capability and provide relatively tight shutoff. The butterfly valve core is a circular disc that rotates about a vertical axis perpendicular to the pipeline axis. When the disc plane is aligned with the pipe axis, the valve is fully open; when the disc plane is perpendicular to the pipe axis, the valve is fully closed. Butterfly valves have short body lengths and low flow resistance, and are more expensive than gate valves and globe valves.

Hydropa valve accessories

Valves and fittings are used for pipeline connections or control systems; neither valves nor fittings can exist independently, as they complement each other. Valves and fittings are available in carbon steel and stainless steel, as well as PVC and other materials. The first two are the most commonly used. In recent years, with improvements in living standards, demand for processed food has increased accordingly. This has driven the rapid development of food machinery, leading to a boom in the production of sanitary stainless steel valves and fittings. When people refer to valves and fittings, they are often referring to sanitary stainless steel products.

Hydropa valve specification considerations

Acceptance follows HG 20202-2000 "Code for Construction and Acceptance of Degreasing Engineering." Before assembly, each component is wiped with clean precision filter paper; selecting dead corners of the components, no color change on the filter paper indicates compliance. 1) The valve model shall indicate the applicable national standard number. If an enterprise standard applies, relevant model descriptions shall be provided. 2) The valve working pressure shall be ≥ the pipeline working pressure; without affecting price, the valve's allowable working pressure should exceed the actual pipeline working pressure. 3) Valve manufacturing standards shall specify the applicable national standard number; if an enterprise standard applies, enterprise documentation shall be attached to the procurement contract.

Hydropa valve common faults

In continuous service, the rubber elastomer in butterfly valves may experience tearing, wear, aging, perforation, or even detachment. Traditional hot vulcanization processes are ill-suited for on-site repair, requiring specialized equipment and consuming significant thermal and electrical energy, which is time-consuming and labor-intensive. Nowadays, polymer composite material methods are gradually replacing traditional methods, with the FoShiLan technology system being the most widely applied. Its products offer superior adhesion and excellent wear and tear resistance, ensuring that repaired components achieve or even exceed the service life of new parts, significantly reducing downtime.
