SKE GVR Series Filter Pressure Regulator

Product Overview

The SKE GVR Series Filter Pressure Regulator is an industrial-grade pneumatic auxiliary component that combines high-precision filtration with highly reliable pressure regulation.SKE GVR30~GVR60 series is engineered for demanding process-industry applications with extremely stringent requirements on control air supply. By seamlessly integrating a 5-25 μm precision filter element with a high-efficiency relieving-type pressure-regulating structure, SKE the GVR series not only significantly saves on-site piping installation space but also effectively blocks moisture, oil contamination, and micron-level dust particles in compressed air. It operates stably in environments from -5°C to 60°C, continuously delivering clean air with extremely low fluctuation (0.05 to 0.85 MPa) to downstream high-sensitivity pneumatic actuators.

Core Advantages and Features:

1. Integrated, Ultra Space-Saving Design:Physically integrates the air filter and pressure regulator, greatly reducing the layout footprint of the pneumatic control panel while eliminating intermediate connecting fittings, reducing potential system leakage risk at the source.

2. High-Precision Filtration and Large Water Capacity:Standard equipped with a high-quality filter element rated at 5-25 μm nominal filtration precision. The large-capacity condensate reservoir design, combined with a shatterproof polycarbonate bowl and protective guard, effectively protects downstream precision components from wear and corrosion caused by contaminants and moisture.

3. Highly Reliable Relieving-Type Pressure Regulation System:Employs a professional relieving-type structure. When a pressure surge occurs on the downstream side due to a shock, the system automatically and rapidly vents excess pressure to maintain absolute balance at the set pressure. A pressure rating of up to 1.5 MPa ensures safe operation under extreme conditions.

4. Full-Range Port Sizes and Extensive Accessory Options:The product lineup covers the full range of port sizes from 1/4" to 1", and offers metal/nylon special bowls, pressure gauges with various measurement ranges (including embedded square-type or standalone round-type gauges), and auto drain options for flexible adaptation to complex plant piping networks.

Application Scenarios

1. High-Energy-Density Lithium Battery / Silicon-Carbon Anode Front-End Coating Process

○ Requirements and Fit: Lithium battery coating machines and slurry pneumatic diaphragm valves are extremely sensitive to air supply fluctuations, and any trace oil or water droplets carried in the air supply can compromise the surface uniformity of coatings (such as silicon-carbon anodes). The GVR series' standard 5-25 μm high-precision filtration and relieving-type regulation structure deliver pulsation-free, ultra-clean power air to high-sensitivity pneumatic circuits, eliminating coating thickness anomalies caused by unstable air pressure.

2. Semiconductor and Electronic Equipment Manufacturing Facilities

○ Requirements and Fit: Semiconductor cleaning and lithography equipment in cleanrooms is space-constrained, and pneumatic auxiliary devices entering the cleanroom are subject to strict anti-contamination requirements. The GVR's integrated design greatly saves equipment installation space; its polycarbonate bowl and dust-free construction, combined with a robust maximum supply pressure of 1.0 MPa, are a perfect fit for space-constrained, high-end equipment manufacturing that requires pulsation-free air supply.

3. Fine Chemical Processing and Heavy-Dust Smelting (e.g., Alumina)

○ Requirements and Fit: In heavy-dust sites such as alumina plants, the compressed air network is often contaminated with hard particles and condensate, which can easily jam or damage downstream cylinders or solenoid valves. The GVR's water capacity of up to 45 cm³ (for the AW40/60 class, for example) effectively separates upstream liquid water; an optional metal bowl can also be selected to strongly resist physical impact and chemical vapor corrosion in harsh environments.
