DN15-50 Stainless pressure sustaining valve 0.2-1.5 Bar

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
