DELCO Z641W/H Pneumatic Linear Gate Valve – High Pressure Isolation, Metal/Soft Seal

✅Minimal Flow Resistance: When fully open, the gate retracts completely to create a straight-through flow path, resulting in significantly lower pressure drop than Pneumatic Globe Valves, making it ideal for main line isolation.

✅Extreme Temp & Pressure: Engineered to withstand harsh environments ranging from cryogenic -196°C to high-heat 500°C and pressures up to PN6.4MPa, utilizing metal hard seals (Stellite) or soft seals (EPDM).

✅Pneumatic Piston Actuation: Powered by a double-acting or spring-return piston actuator (4-8 bar supply), providing the high linear thrust needed to seat and unseat the gate against high differential pressures.

✅Optional Insulation Jacket: The valve body can be equipped with an insulation sleeve to prevent medium condensation or heat loss, critical for steam and viscous fluid lines.

✅Tight Sealing: Relying on the downward thrust of the actuator to force the wedge gate between the seats, it achieves a tight seal with low leakage rates, ensuring reliable shutoff.
