SCH8O/DIN Labcock Ball Valve

Selection and application guide of Labbock ball valve in industrial piping system

In industrial piping system, Labbock ball valve is widely used in many key industries due to its reliable sealing, corrosion resistance and long life. Different working conditions have different requirements for the material, pressure level and sealing performance of ball valves. The following is the selection points and application scenario analysis of Labbock ball valve in multiple industries:

1. Safe Drinking Water & Drinking Water
Selection requirements: Use food-grade stainless steel (such as SS316) or EPDM seals to ensure no heavy metal precipitation and meet hygiene standards (such as FDA, WRAS).
Application scenarios: Municipal water supply network, water treatment plant, drinking water delivery system, requiring zero leakage to prevent pollution.

2. Metallurgy industry
Selection requirements: High temperature resistance, wear resistance, valve body material is usually carbon steel or alloy steel, and seals are metal hard seals or PTFE to adapt to high dust and high corrosion media (such as slurry, high temperature flue gas).
Application scenarios: blast furnace cooling system, steel rolling production line, smelter corrosive fluid control.

3. Photovoltaic industry
Selection requirements: high purity, low particle pollution, the valve body is made of ultra-clean stainless steel (SS316L), and the sealing material is PTFE or perfluoroether rubber (FFKM) to prevent silicon material contamination.
Application scenarios: polysilicon production, chemical liquid transportation in solar cell manufacturing process, and high-purity gas control.

4. Nuclear power industry
Selection requirements: radiation resistance, high pressure and high temperature resistance, must comply with ASME III nuclear grade certification, the material is usually stainless steel + graphite seal to ensure reliability under extreme working conditions.
Application scenarios: nuclear island cooling system, radioactive waste liquid treatment, main steam pipeline isolation.

5. Electronic semiconductor
Selection requirements: ultra-high cleanliness, chemical corrosion resistance, the valve body is made of electropolished 316L stainless steel, and the seal can be PTFE or PFA lining to avoid particulate and metal ion contamination.
Application scenarios: wafer manufacturing, etching liquid delivery, ultrapure water (UPW) system.

6. Medicine
Selection requirements: sterile design, easy cleaning (CIP/SIP), the material must meet GMP standards, usually 316L stainless steel + EPDM/FKM seals.
Application scenarios: biopharmaceutical fluid control, water for injection (WFI) system, sterile culture medium delivery.

7. Industrial Water Treatment
Selection requirements: corrosion resistance, anti-scaling, suitable for acid and alkali media, optional PVC lined valve or duplex stainless steel, EPDM or Viton seals.
Application scenarios: circulating cooling water, reverse osmosis (RO) system, chemical dosing device.

8. Industrial Wastewater
Selection requirements: corrosion resistance, wear resistance, the valve body material can be cast iron epoxy coating or duplex steel, PTFE or NBR seals are used, suitable for wastewater containing particles and high salt.
Application scenarios: sewage treatment plants, electroplating wastewater treatment, chemical wastewater discharge systems.

Summary of key factors in selection
Medium characteristics: corrosiveness, particle content, temperature/pressure.
Material matching: stainless steel, alloy, plastic lining selection.
Sealing technology: soft seal (EPDM, PTFE) or metal hard seal.

Industry certification: such as ASME, FDA, GMP, nuclear grade standards, etc.
