Description
Direct Acting Flanged Pressure Sustaining Valve – Z Tide Industrial Series RFF
Heavy-duty direct-acting back pressure valve designed for industrial systems requiring precise upstream pressure maintenance.
Key Features
→ Function: Pressure sustaining / back pressure valve (BPV)
→ Operation: Direct acting
→ Port Sizes: DN15, DN20, DN25, DN40, DN50, DN65, DN80, DN100, DN150
→ Flange Type: PN16 standard; optional JIS10K, ANSI150Lb, or PN25
→ Max Inlet Pressure: 25 Bar
→ Back Pressure Adjustment: 1–5 Bar or 4–10 Bar, indicated via stainless steel pressure gauge (included)
→ Test Pressure: 35 Bar
→ Temperature Range: -15°C to +80°C
Materials & Construction
→ Body: 316 stainless steel standard; Duplex 316 stainless steel optional
→ Flanges: CF8M for DN65–DN100; other sizes welded 316L stainless steel
→ Internals: Stainless steel
→ Seals: NBR standard; optional Viton or EPDM
→ Media Compatibility: Air, water, pure water, light oil, and other fluids/gases <40 cSt compatible with materials of construction
Performance & Design
→ Maintains pre-set back pressure upstream:
• If upstream pressure drops to set value → valve begins to close to sustain pressure
• If pressure rises → valve opens to allow flow again
→ Designed for critical upstream systems, limiting flow to non-critical downstream systems when required
Applications:
→ Ideal for chemical plants, water treatment, compressed air systems, and process lines requiring precise pressure control for safety and process stability.
