We are a professional manufacturer of high-precision custom valve parts and valve components for industrial fluid control, oil & gas, chemical and marine industries. Our main products cover valve stem, valve core, valve disc, valve seat and valve base. We adopt high-grade special materials including SS316 stainless steel, 17-4PH precipitation hardening stainless steel and D2 tool steel to ensure high hardness, wear resistance and corrosion resistance.
We support one-stop custom services including precision CNC machining, professional heat treatment and various surface treatments. All valve parts are strictly produced under high-standard tolerance control, suitable for high pressure and high temperature working conditions. We provide OEM & ODM customized valve components for global clients.
We use multiple high-performance special materials for custom valve components:
SS316 Stainless Steel: Excellent corrosion resistance, acid and alkali resistance, widely used for marine, chemical and sanitary valve parts.
17-4PH (17-4) Stainless Steel: High strength, high hardness and good mechanical properties after aging heat treatment, ideal for high-pressure valve stems and core components.
D2 Tool Steel: Super high hardness and wear resistance, suitable for wear-resistant valve disc and valve base under severe working conditions.
We provide full-process supporting services for custom valve parts:
1. Precision CNC Machining: Turning, milling, drilling, tight tolerance machining to ensure high dimensional accuracy.
2. Professional Heat Treatment: Hardening, tempering, solution treatment, aging treatment, improving material hardness and toughness.
3. Surface Treatment: Polishing, passivation, sandblasting, anti-rust treatment, improving surface finish and corrosion resistance
