Gas Station Fuel Tank Angle Check Valve
our angular check valve 40mm/50mm is a specialized flow control device approved by all major oil companies in china. designed for liquid applications, particularly petroleum products like ldo, hsd, kerosene, furnace oil, and biodiesel, this valve ensures reliable performance in suction pump systems.
This is a great check valve/angle valve for submersible pump oil pipelines. Threaded installation interface, 1.5 inches (DN40), thread inner diameter of about 45mm or 2 inches (DN50) thread inner diameter of about 56.6mm, (commonly used are NPT tapered thread installation requires appropriate filler or thread glue seal, BSPT/British G thread and BSPF straight thread) Cast iron valve body, copper valve core, oil-resistant valve disc, is an indispensable and practical component for submersible oil pump refueling machine.
Brief appearance dimensions:
1.5 inches/DN40=115*110*81mm
2 inches/DN50=121*110*80mm
key features:
- material excellence: constructed with gunmetal valve seats and rubber poppets, ensuring minimal wear and extended lifespan.
- optimized suction: lightweight rubber poppets reduce resistance in suction lines, enabling smoother fluid transfer.
- spark-free operation: critical friction points use cast iron/brass or mild steel/neoprene rubber combinations to prevent ignition risks.
- environmental adaptability: functions effectively between -25°c and +100°c, accommodating extreme temperature conditions.
- pressure resilience: withstands up to 60 lbs of pressure load for robust performance.
application specifics:
- installed at the top of underground storage tanks in dispensing systems.
- liquid enters through the base, makes a 90° turn, and exits, hence the "angular" designation.
- prevents backflow in suction pumping systems, critical for service stations and commercial fueling facilities.
manufacturing process:
- produced under strict supervision using premium raw materials and advanced technologies.
- rigorously tested by quality control teams to meet industry standards.
market validation:
- trusted by leading oil companies and widely adopted in fueling infrastructure across china.
- preferred for its ease of maintenance and compliance with safety regulations.
this valve addresses critical challenges in petroleum handling, balancing durability, safety, and operational efficiency.
