Product Overview
The High Pressure Stainless Steel Air Release Valve For Industry is a professional heavy-duty venting component independently developed for industrial high-pressure closed circulation pipeline systems. Different from conventional PN10/PN16 medium and low-pressure air vents suitable for civil and conventional industrial scenarios, this product adopts a PN40 high-pressure grade design, focusing on solving air accumulation hazards in high-pressure pressurized pipelines that ordinary air vents cannot adapt to.
The entire valve body adopts thickened integrated stainless steel forging process, with enhanced wall thickness and structural rigidity, which can resist continuous high-pressure impact and instantaneous pressure surge in industrial pipelines. The internal core assembly is upgraded with high-pressure resistant floating body and reinforced composite sealing pair, abandoning the fragile structural design of ordinary civilian vents. It maintains stable mechanical sensitivity and no leakage sealing performance under long-term high-pressure operating conditions.
Adopting pure mechanical buoyancy automatic working mode, no power supply and no manual intervention are required. It can continuously and effectively discharge free accumulated air, micro-bubbles and gas separated from high-pressure fluid in pipeline pressure maintaining operation, water filling, fluid replacement and pressure fluctuation cycles. It thoroughly solves industrial common problems such as high-pressure air lock, pipeline pressure instability, reduced fluid delivery efficiency and abnormal equipment vibration. It is specially suitable for harsh industrial scenarios with high operating pressure, frequent pressure changes and strict pipeline safety standards.

•Strict Working Condition Compliance — The rated working pressure is PN40(4.0MPa). Long-term over-pressure operation is prohibited to avoid structural fatigue and leakage of the valve body and sealing components.
•Regular High-Pressure System Inspection — For long-term running industrial high-pressure systems, regularly check the valve body for leakage and vent port patency. Timely clean surface dirt to ensure sensitive automatic venting response.
•Prohibited Special Media — It is not suitable for strong acid, strong alkali and high-concentration corrosive media and high-viscosity impurity-containing fluids to prevent internal structural corrosion and blockage.
•No Unauthorized Disassembly — The internal high-pressure matching structure is professionally calibrated. Private disassembly and assembly will destroy the pressure-resistant balance and sealing performance, leading to high-pressure failure risk.
