Pneumatyczny zawór bramkowy DELCO Z641W/H do pracy w wysokich temperaturach, Kontrola włączenia/wyłączenia przy wysokim ciśnieniu

✅ Minimal Flow Resistance (Full Bore): Gdy jest całkowicie otwarty, the gate valve provides a straight-through flow path with the gate completely lifted out of the media stream. This results in negligible pressure drop across the valve, making it highly energy efficient for high-volume liquid and gas transport.

✅ Extreme Environment Suitability: Built to withstand severe industrial conditions, this valve is suitable for cryogenic services down to -196 ℃ and high-temperature steam/oil up to 500 ℃ (material dependent). Options include insulation sleeves to prevent media condensation.

✅ High-Pressure Cut-Off Capability: Available in pressure classes up to PN6.4 (6.4 MPa). The closing action requires an external force (from the actuator) to seat the gate, ensuring a tight shut-off, available with metal hard seals (np., Stellite alloy welding) or EPDM soft seals.

✅ Pneumatic Automation: Operated by a powerful Pneumatic Piston Actuator (gas source 4-8 bar), the valve provides fast and reliable on/off function. Available in Double Acting (powietrze otwieranie/powietrze zamknięte) lub Single Acting (Reset sprężyny) Konfiguracje.

✅ Durable Construction and Size Range: Main components (Body and Gate) are available in Stainless Steel 304/316 and WCB for strength and corrosion resistance. Sizes range from DN50 up to a large DN500, accommodating most industrial pipeline sizes.
