Maria Valve
1 / 5
| Product Name | Needle Valve |
| Manufacturing Process | Forged |
| Applicable Medium | Oil / Gas / Water / Corrosive Medium |
Manufactured from 304 Stainless Steel, it offers excellent corrosion and oxidation resistance. It maintains stable mechanical performance across a wide temperature range for water, oil, and gas.
Features an M20×1.5 metric fine thread. This ensures strong sealing performance, high vibration resistance, and easy installation or disassembly.
The stem moves smoothly, providing operators clear tactile feedback when the valve plug contacts the seat, preventing overtightening and seat damage.
The model number 160P denotes a nominal pressure rating of PN160 (16 MPa / approx. 160 bar). The precision-forged body ensures long-term stable operation under high-pressure conditions.
A needle valve is designed to precisely control the flow rate and pressure of fluids. It achieves fine adjustment of small flow rates and cuts off fluid flow effectively with superior sealing performance.
Its working principle involves rotating the valve stem to move a needle-shaped core. As the gap between the core and seat changes, the fluid passage is precisely adjusted or completely sealed.
Technical communication, model selection to minimize cost and maximize efficiency, and customized improvements for special requirements.
Guaranteed delivery on time with quality inspections. Technical personnel can provide on-site guidance and structural documentation.
12-month product warranty. Fast response within two hours for any discrepancy or quality issues during acceptance.
Full support for repair, return, and replacement under normal storage and use conditions if quality problems occur.
