Self-Sealing Globe Valve

Self-Sealing globe valves use the system's own pressure to tighten the bonnet seal, meaning the higher the pressure, the tighter the seal becomes. 
Specific Applications
Self-Sealing globe valves are commonly found in power plants, petrochemical facilities, and metallurgical plants. They handle high‑temperature, high‑pressure steam in blowdown, drain, and boiler blowdown systems.
Key Features
Self‑Sealing Pressure Seal Design – The higher the system pressure, the tighter the bonnet seal. This self-sealing globe valve uses the media’s own pressure to energize the seal – eliminating external leakage.
Heavy‑Duty Industrial Construction – Rated Class 900 to 4500, -40°C to 600°C. As a true self-sealing globe valve, it is built for industrial and heavy‑duty applications – power plants, petrochemical facilities, metallurgical plants, blowdown, drain, and boiler blowdown systems.
Integrally Forged Body & Seat – One‑piece forged body and seat with separate disc and stem. Provides superior strength and leak‑tight integrity under extreme conditions.
Three Flow Configurations Available – Straight‑pattern (highest resistance), Y‑pattern (lower resistance, ideal for steam), and angle‑pattern (compact for high‑pressure service). Choose the best fit for your system.
Tested & Customizable – Body materials: carbon steel, stainless steel, or alloy steel. End connections: butt weld, socket weld, or flanged to DIN, ANSI, JIS, or BS. Drain plugs or accessories available per service requirements.
Quality Certification
We hold ISO 9001, ISO 14001, and ISO 45001 certifications, plus a special equipment production license (TS). Our products are made to API, ANSI, JIS, ISO, BS, JB, and GB standards. This covers material checks, non‑destructive testing, precise measurements, and valve strength/sealing performance.
Custom Manufacturing Services
You send us a drawing or sample, and we review the requirements. Then we confirm the drawing and give you a quote — faster if you provide a 3D model. After order confirmation, we schedule batch production.
