How much is the price difference between soft seal butterfly valve and hard seal butterfly valve?

This article analyzes the price difference between soft seal and hard seal butterfly valve and the core difference. Hard seal butterfly valve price is usually higher than soft seal, DN300 caliber below the price difference of about 100-900 yuan (depending on the model). Key differences include: soft seal (rubber/polyurethane material, excellent sealing performance but short life, suitable for water/air and other conventional media); hard seal (metal material, high temperature and pressure, long life, suitable for chemical/petroleum and other harsh environments). Selection should be based on engineering needs and media characteristics to ensure system safety and efficiency.

Key valves for air-conditioned pump rooms: butterfly valves

With the advantages of simple structure, compact size and low cost, the centerline butterfly valve has become a key valve in air-conditioned water pump rooms. It efficiently controls water flow (opening/closing/regulating) by rotating the butterfly plate and provides reliable sealing in low-pressure water systems, meeting the space and functional requirements of the pump room and guaranteeing stable system operation.
