Isolation Style Gates

Plattco invented the isolation series valve in the 1980s.  Its main purpose is to be used as a shut off isolation valve for the main fuel feed lines of coal boilers.  The valve has a unique ramping action in the closed position to provide a near air tight seal when closed.  On the fuel feed line this keeps the positive pressure from the boiler below form escaping, allowing the coal feed equipment upstream of the valve to be repaired safely.

Companies around the world choose Plattco maintenance gates because they will:

• Effectively and reliably close and seal against material
• Perform in critical, demanding condition
• Offer Convenient & Inexpensive Maintenance for decades of like-new operation

Operating Parameters:

• Maximum temperature capability is 1500F air, ambient temperature materials
• Maximum pressure capability of 15 psi / 1 BAR
• Handles dry powder materials

Excellence in Design:

• Cast valve housing made from ASTM A 297 grade HT material withstands the temperature demands of the fuel feed system
• Standard and custom sizes available, ability to match any flanges and transition to equipment above/below
• High chrome internal sliding gate is both abrasion and heat resistant, allowing the valve to reliably operate for years
• In-line removable and replaceable rollers and/or pins, actuation, sliding blade (gate) and packing glands to ensure no leakage to atmosphere
• Unique packing gland on the valve stem ensures no leakage to atmosphere, quick & easy maintenance without pulling it out of line
• Gate ramps lift the gate into position at the end of stroke ensuring a tight air seal when the valve is closed
• Cylinder design offers capability of adding open / closed indicator switches
• Variety of actuation available including pneumatic, electric, hydraulic, screw jack and hand-wheel
• Multitude of available accessories including indicator switches, guards, control packages, and filter regulators
