What Is the Price Difference between Soft-Sealed and Hard-Sealed Butterfly Valve

This article analyzes the price differences and key distinctions between soft-sealed and hard-sealed butterfly valves. Hard-sealed butterfly valves are typically more expensive than soft-sealed ones; for sizes below DN300, the price difference is approximately 100–900 yuan (depending on the model). Key differences include: soft-sealed (rubber/polyurethane material, offering excellent sealing performance but a short service life, suitable for conventional media such as water and air); and hard-sealed (metal material, resistant to high temperatures and pressures with a long service life, suitable for harsh environments such as chemical and petroleum industries). Selection must be based on engineering requirements and media characteristics to ensure system safety and efficiency.

Key Valves in the Air Conditioning Pump Room: Butterfly Valve

Thanks to their simple design, compact size, and low cost, center-line butterfly valves have become essential valves in air conditioning pump rooms. By rotating the disc, they efficiently control water flow (opening, closing, and regulating) and provide a reliable seal in low-pressure water systems, meeting the space and functional requirements of pump rooms and ensuring stable system operation.
