German ARI valve ARI model ARI price

ARI valves serve an on/off function. They are commonly installed at the inlets and outlets of cold and heat sources, equipment inlets and outlets, and pipeline branches (including risers), and 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 into rising stem and non-rising stem, single disc and double disc, wedge disc and parallel disc types. 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 have a wide range of nominal diameters. Globe valves are classified into straight-through, angle, and Y-pattern types based on media flow direction, with rising stem and non-rising stem variants. 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 operated so that the bore of the sphere aligns with the pipeline axis, it is fully open; rotating 90° results in full closure. Ball valves have certain throttling capabilities and provide relatively tight shutoff. The butterfly valve core is a circular disc that rotates around a vertical axis perpendicular to the pipeline axis. When the plane of the disc is aligned with the pipe axis, it is fully open; when the disc plane is perpendicular to the pipe axis, it is fully closed. Butterfly valves have short body lengths, low flow resistance, and are more expensive than gate valves and globe valves.

ARI valve related accessories

Valves and fittings are used for pipeline connections or control systems. Valves and fittings cannot exist independently; they are complementary. Valve fittings are available in carbon steel and stainless steel, as well as PVC, or other materials. The first two are the most common. In recent years, with the improvement of living standards, demand for processed food has increased. This has driven the rapid development of food machinery, leading to a boom in the production of stainless steel sanitary valves and fittings. When people refer to valve fittings, they mostly mean stainless steel sanitary grade products.

ARI valve specification precautions

Acceptance follows HG 20202-2000 "Code for Construction and Acceptance of Degreasing Engineering". Before assembly, each component is wiped with clean precision filter paper; if the filter paper does not change color when wiping dead corners of the component, it is considered qualified. 1) The valve model should indicate the required national standard number. If it is an enterprise standard, relevant specifications for the model should be noted. 2) Valve working pressure must be ≥ the pipeline working pressure; without affecting the price, the pressure the valve can withstand should be greater than the actual working pressure of the pipeline. 3) Valve manufacturing standards should specify the applicable national standard number; if it is an enterprise standard, enterprise documentation should be attached to the procurement contract.

ARI valve common faults

Rubber elastomers in butterfly valves may experience tearing, wear, aging, perforation, or even detachment during continuous use. Traditional hot vulcanization processes are difficult to adapt to on-site repair needs, requiring specialized equipment, consuming significant thermal and electrical energy, and being 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 possess superior adhesion and excellent wear and tear resistance, ensuring that repaired components meet or even exceed the service life of new parts, significantly reducing downtime.
