The Magpies faced off against a Burnley Women side they'd already met twice earlier in the season, and Langley's side came out on top after a dominant second half display.
United were backed - as usual - by a large away following who helped roar Newcastle on to a huge three points, with substitute Kacie Elson giving Newcastle the lead before Paige-Bailey Gayle and Jasmine McQuade sealed the victory.
"It did feel like a home game with so many Geordie fans," Langley admitted. "We are super proud and grateful for them."
Three goals and a clean sheet saw Newcastle make a statement to the rest of the FA Women's National League Northern Premier Division as they look to kick on in the final stretch of this competitive campaign.
"I was really happy with a clean sheet, a good performance overall and a really confident second half that we stepped on with," said Langley. "I'm absolutely delighted with three points.
"When Kacie came on I thought she was really impactful; she was there really quick to react from (Charlotte) Pottsy's free kick and then it's 1-0.
"I thought the subs came on and impacted things positively."
It was a massive win for Newcastle, but Langley was keen to reiterate that it was only three points and the season is far from being over.
"You feel good when you win your head-to-heads and that should give us confidence," Langley added. "But we need to stay consistent."
United return to Kingston Park this weekend and welcome fifth-placed Derby County Women, who they beat away from home in September thanks to a Bridget Galloway strike.
Despite the gap in the table between the two sides, Langley was keen to emphasise how important every game is from now until the end of the season.
"The three points we got against teams at the bottom of the table are the same as the ones off the teams at the top.
"I'm really looking forward to it. Derby was a tough test for us when we played them away from home, winning the game 1-0.
"So we're expecting another tough test and we'll be preparing the same."
