Product Introduction & Key Selling Points
Z45X(RVHX) Non-Rising Stem Resilient Seated Gate Valve is a professional shut-off valve independently developed for medium and large-diameter fluid pipeline systems. It features elastic seat sealing and a non-rising stem design, effectively solving leakage and space constraints in traditional water supply and drainage projects. Manufactured in strict compliance with GB/T12232 & CJ/T216 standards, each valve undergoes 100% hydrostatic strength and sealing tests, ensuring reliable performance in harsh conditions like municipal pipelines and industrial circulation water systems.
Key Selling Points:
- Complies with GB/T12232 & CJ/T216 standards, 100% pressure tested
- Non-rising stem design, ideal for limited vertical space
- Ductile iron QT450 body with epoxy coating for superior corrosion resistance
- EPDM encapsulated wedge provides bubble-tight sealing for water and oil media
- Dual pressure ratings: PN10 (1.0MPa) and PN16 (1.6MPa)
- Full size range from DN50 to DN1000, with customizable flange standards (GB/DIN)
- Low-torque handwheel operation, maintenance-free for over 5 years
- Ideal for municipal water supply, sewage treatment, and fire protection systems
Core Advantages (Based on Technical Specifications)
- Standardized Manufacturing: Designed by GB/T12232 & CJ/T216, flanged connection conforms to GB/T17241.6 and JB78, pressure tested by GB/T13927, fully meeting the quality requirements of international engineering projects.
- Dual Pressure Adaptability: Supports two working pressure levels—PN10 (1.0MPa) and PN16 (1.6MPa), with sealing test pressure up to 1.76MPa and strength test pressure up to 2.4MPa, strong pressure bearing capacity.
- Durable Material Structure: Valve body and bonnet are made of ductile iron QT450, internal and external epoxy resin coating, resistant to rust and chemical corrosion; gate plate is wrapped with high-quality EPDM rubber, realizing zero leakage sealing.
- Space-Saving Design: The dark rod structure makes the valve stem rotate inside the valve body without lifting, and the overall height is fixed, which is especially suitable for underground pipelines and equipment with limited vertical space.
