Description
316 Stainless Steel Low-Pressure Flanged Sustaining Valve – Z-Tide Industrial Series RFLF
Precision direct-acting pressure sustaining (back pressure) valve designed for low-pressure systems requiring stable upstream pressure.
Key Features
→ Function: Pressure sustaining / back pressure valve (BPV)
→ Operation: Direct acting
→ Port / Flange Sizes: DN15, DN20, DN25, DN40, or DN50 PN16; optional ANSI 150Lb or JIS10K flange
→ Back Pressure Adjustment: 0.2 – 1.5 Bar, displayed on included stainless steel pressure gauge
→ Max Inlet Pressure: 5 Bar
→ Test Pressure: 16 Bar
→ Temperature Range: -15°C to +100°C (seal dependent)
Materials & Construction
→ Body: 316 stainless steel; optional Duplex 316 stainless steel
→ Internals: Stainless steel
→ Seals: NBR standard (+60°C), optional Viton (+100°C) or EPDM
→ Media Compatibility: Air, water, pure water, light oils, and fluids under 40 CST compatible with valve materials
Performance & Design
→ Maintains a pre-set back pressure upstream; valve closes when pressure drops below the setpoint and opens when pressure rises
→ Pressure gauge provides real-time indication of upstream/back pressure
→ Balanced design ensures stable, repeatable pressure control regardless of fluctuations in inlet pressure
Applications
→ Industrial process water systems and RO lines
→ Low-pressure air or fluid systems requiring precise upstream pressure control
→ Laboratories, chemical, and light oil applications where back pressure must be maintained
