Description

Direct Acting Pressure Sustaining Valve – Z Tide Industrial Series RFT

High-precision direct-acting back pressure valve (BPV) designed to maintain a stable upstream pressure in industrial and fluid systems.

Key Features
→ Function: Pressure sustaining / back pressure valve (BPV)
→ Operation: Direct acting
→ Port Sizes: 1/2, 3/4, 1, 11/2, or 2 BSPT; optional NPT or BSPP (G) thread
→ 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 +100°C (dependent on seal material)

Materials & Construction
→ Body: 316 stainless steel standard; Duplex 316 stainless steel optional
→ Internals: Stainless steel
→ Seals: NBR +60°C standard; optional Viton +100°C 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 pressure drops to set value → valve begins to close to sustain back pressure
 • If pressure rises → valve opens to allow flow again
→ Designed for critical upstream systems, limiting flow to non-critical downstream systems if required

Applications:
→ Ideal for water treatment, compressed air systems, light oil circuits, chemical processes, and other industrial applications requiring precise upstream pressure control.
