Kent Non-Lubricated Plug Valves

Kent Non-Lubricated Plug Valves are designed for durability, reliability, and ease of maintenance. These sleeved quarter-turn plug valves achieve bubble-tight sealing through a high-performance PTFE sleeve that completely encapsulates the plug. The result is a valve that delivers virtually maintenance-free operation for decades in demanding applications.

Key Features & Benefits

• Maintenance-Free Design – In-line serviceability with minimal wear ensures extended service life.
• Reliable Sealing – The PTFE sleeve provides a large circumferential sealing surface, ensuring tight shut-off in open, closed, or rotating positions.
• Self-Cleaning Action – 360° port lips clean the sealing surface as the plug rotates, reducing scaling and buildup.
• Versatile Applications – Suitable for both on/off and throttling service across multiple industries.
• Compact & Lightweight – Simple actuation, bi-directional flow, and multiport configurations optimize system design.
• Reduced Friction – The sleeve minimizes plug-to-body contact, lowering torque requirements and extending valve life.

Typical Applications

• Petroleum refining and petrochemicals
• Chemical and pharmaceutical industries
• Fertilizer production
• Power generation systems
• Services involving sulfur, hydrogen fluoride, or media prone to crystallization or clogging

Limitations

While offering excellent sealing and low-maintenance operation, non-lubricated plug valves are limited by the temperature and chemical compatibility of their non-metallic sleeve materials. Proper material selection ensures optimal performance.
