Approvals

Features

• Maximum working pressure Class 900 (PN150) per marketing text; pressure range stated elsewhere as Class 150-2500
• Bidirectional sealing via precisely ground gate plates and valve seats
• Full-diameter bore structure for low flow resistance and minimal pressure drop
• Alloy steel body and internals with surface hardening for corrosion and wear resistance
• Self-lubricating valve seats to reduce wear and extend maintenance intervals
• Flat gate plate design enabling two-way sealing
• Fire-safe design per API 6A

Notes

• Maximum working pressure stated in Features section as Class 900 (PN150), but Technical Specification and General Information indicate pressure range up to Class 2500 — verify applicable pressure ratings with supplier.

Description

A slab gate valve designed for high-pressure pipeline systems in petroleum, natural gas, and chemical engineering applications. The valve body is constructed from alloy steel with surface hardening treatment, and features a flat gate plate design enabling bidirectional sealing with full-diameter, low-resistance flow path. Suitable for operation under high pressure, high temperature, and corrosive medium conditions.
