Industrial valves

Industrial valve equipment comprises a range of stainless steel components such as faucets, valves and actuators, valves, check valves, fittings, and pressure control devices used for fluid transportation. These components are used in sectors like food and beverage, chemical and agrochemical industries, water treatment and distribution, energy production, and construction. 

Valves and connections used in industrial valve systems must meet stringent requirements for hygiene, food safety, temperature and pressure resistance, and fluid compatibility to ensure efficient and safe fluid handling. 

Consequently, seals ensuring the sealing in valves must meet these constraints and possess industry-specific certifications.
