SEDELON Manufactured DBB BALL VALVES

Sedelon pays much attention on quality control in products, and all valves are designed and tested according

Pressure Seal Gate Valve vs Bolted Bonnet: High-Pressure Steam Service Selection

A pressure seal gate valve uses line pressure to tighten a self-energizing gasket, so the joint seals tighter as steam pressure rises; a bolted bonnet clamps the joint with studs and needs ever-larger studs at high pressure. This guide compares the two designs on sealing, pressure class, temperature, maintenance and cost, and how to specify the right gate valve.

API 6D Ball Valve vs API 608 Ball Valve: Pipeline vs Process Service Standards

API 6D and API 608 ball valves look alike but serve different worlds. API 6D governs pipeline valves with butt-weld ends and full mill certification; API 608 covers refinery and process-plant ball valves, usually flanged in smaller bores. This guide compares end design, pressure class, fire safety, sour service and documentation, and how to choose the right standard.

Swing Check Valve vs Lift Check Valve: Backflow Prevention Selection Guide

A check valve stops backflow with no actuator. A swing check uses a hinged clapper for very low pressure drop on horizontal, large-bore lines; a lift check uses a guided disc that seats squarely for tighter, faster shut-off in vertical and high-velocity runs. This guide compares the two on sealing, pressure drop, orientation and water hammer risk.
Triple Offset vs Double Offset Butterfly Valves

Triple Offset Butterfly Valve vs Double Offset: Severe Service Selection Guide

Triple offset or double offset butterfly valve? The deciding question is whether the service needs fully metal-seated, zero-leakage, fire-safe isolation, or a resilient-seated throttling valve that is cheaper to run. This guide explains how the offsets work, where each design wins, and how to specify the right one for severe-service lines.
