Price Reference for DN100 Lever Safety Valve
Prices for DN100 lever safety valves vary significantly based on material grade, pressure rating, and configuration:
Standard GA42H single lever safety valves with DN100 configuration are available from approximately 2,000 to 3,000 CNY depending on pressure rating and supplier . Premium double lever models such as GA44H-16C for steam service are priced at approximately 3,600 CNY .
Economy lever safety valves from smaller manufacturers are available from approximately 499 CNY for basic DN100 configurations, offering cost-effective solutions for non-critical low pressure applications .
Flanged lever safety valves with full lift design for high discharge capacity are available from approximately $100 USD (approx. 700 CNY) for bulk orders of 20 pieces or more, with significant cost advantages for large projects .
Key factors affecting price include material grade (cast iron vs bronze vs stainless steel), pressure rating, valve type (single vs double lever), and certification requirements.
Understanding Lever Safety Valve Design
Lever safety valves, also known as lever-and-weight safety valves, operate on a simple and reliable principle. A weight mounted on a lever arm applies a downward force that holds the valve disc closed against system pressure . When system pressure exceeds the set point, the pressure force overcomes the lever force, opening the valve to relieve excess pressure .
This design offers several advantages for low pressure applications. The set pressure can be easily adjusted by moving the weight along the lever arm, making field adjustment straightforward and requiring no specialized tools. The simple mechanical design ensures long-term reliability with minimal maintenance requirements. The lever mechanism also enables manual lifting for periodic testing and system verification.
Technical Specifications
DN100 lever safety valves typically handle pressure ratings up to PN16 (1.6MPa), with temperature capability up to 450°C for carbon steel models and up to 220°C for bronze models . Body materials include carbon steel WCB, bronze, and stainless steel options based on service requirements . Available in single lever or double lever configurations, with full lift design providing maximum discharge capacity for steam and gas applications . Flanged connections per ANSI, DIN, or GB standards are standard.
Low Pressure High Flow Applications
Lever safety valves serve critical functions in steam boilers, compressed air systems, pressure vessels, heating systems, and process equipment handling air and steam media requiring low pressure protection . The lever mechanism provides reliable operation at pressures as low as 0.05MPa.
Summary
DN100 lever safety valves provide reliable overpressure protection for low pressure high flow applications, with prices ranging from approximately 499 CNY for economy models to 3,600+ CNY for premium configurations. The simple lever mechanism enables easy set pressure adjustment and manual testing. Selection requires careful evaluation of pressure rating, temperature capability, and material compatibility based on specific application requirements.
