This butt weld angle needle valve is forged as a single piece with a butt weld end, so there is no welding-stress concentration at the body joint, and the angle pattern directs the flow through a compact 90-degree turn. It is built for fluid control under high vibration of up to 50 Hz, typical of hydraulic branches on excavators, cranes and other construction machinery. The stem carries a wear-resistant alloy coating about 50 microns thick, and the sealing structure passes a 1000-hour anti-vibration test. Threaded ports range from M16x1.5 to M30x2, pressure ratings run from 16 to 32 MPa, and low-temperature materials down to -40 degrees Celsius are available for cold-region equipment.
When this valve is welded into a machine's hydraulic line, the buyer cannot simply swap in a stock part later, so the weld end and body quality are decided before installation. We forge and test the body as one assembly, and the anti-vibration seal is verified for 1000 hours so the valve does not become the weak point of a welded circuit. For OEM customers who spec this valve into their own machines, we keep the weld-end geometry and thread range on file and reproduce the same configuration on repeat orders, which removes re-qualification work.

Applications
- Hydraulic branches on excavators and cranes: the forged body and vibration-tested seal survive continuous machine shock.
- High-pressure fixed lines: butt weld end becomes integral with the pipe, eliminating threaded joints that can loosen.
- Cold-region equipment: low-temperature material versions keep the valve ductile at -40 °C.
Customization
Weld-end geometry, port size, stem coating and low-temperature materials can be produced from drawings or samples. OEM production with fixed configurations for repeat orders is supported.
Packaging & Transportation
Moisture-proof export cartons with cushioning; wooden crates for large orders. We support EXW, FOB, CIF, CFR, DAP and DDP.
FAQ
Q: Can you manufacture based on our technical drawings or prototypes?
A: Certainly, we can manufacture based on your technical drawings or prototypes.
Q: What is the lead time for repeat orders?
A: Since technical processes and materials are already prepared for repeat orders, the production cycle can typically be shortened by about 30%-50%.
Q: What is your custom-made products payment term?
A: 50% deposit in advance, 50% balance payment.
