Product Description

The durable Russian Standard Gate Valve manufactured by JQF Valve is widely used in the inlet and outlet channels or media shut-off devices of oil and steam pipelines in petrochemical, thermal power and other industries. It has passed CE certification, is of high quality and durable, and ensures compliance with EU safety standards, guaranteeing market access compliance.

1. Space-Optimized Fluid Dynamics Architecture: The structurally optimized chassis design provides the valve body with exceptional rigidity and unobstructed flow geometry, minimizing pressure drop.
2. Advanced Composite Sealing Surface: The Russian Standard Gate Valve utilizes proprietary metallurgical technology to combine corrosion-resistant alloys with a tungsten carbide matrix, achieving an exceptionally long cycle life far exceeding industry standards.
3. Friction-Free Stem Operating System: Anisotropic graphite packing rings ensure a zero-leakage stem seal while providing a clear, low-torque actuation for easy and effortless operation.
4. Multi-Mode Actuation Integration: The Russian Standard Gate Valve offers comprehensive actuation compatibility, including manual handwheels, pneumatic actuators, electric motors, and planetary gear reducers, enabling universal deployment.
5.Configurable Valve Disc Topology Platform: Three different sealing configurations: pressure-adaptive flexible single gate, high-load rigid single gate, and bidirectional dual parallel gate.
