The operation of a PRV is based on a simple yet effective mechanical principle. When the inlet pressure exceeds the setpoint of the valve, the internal mechanism adjusts to reduce the pressure to the desired level. Typically, this involves the use of a spring-loaded diaphragm or piston that moves in response to changes in pressure. As the upstream pressure increases, the diaphragm is pushed against the spring force, causing the valve to partially close until the outlet pressure stabilizes at the preset value.

  • Wrought iron is also a fantastic material for artistic projects. Its flexibility allows for it to be fashioned into various decorative items such as wall art, candle holders, or even custom furniture pieces. 

  • The stakes are high, and with both materials boasting their own sets of advantages, the decision-making process can feel overwhelming. Below, we’ll compare and contrast these two choices against the most important criteria: aesthetics, cost, durability, security, and more.

  • In addition to their aesthetic appeal, wrought iron fence ornaments offer a practical advantage. Their robust nature ensures longevity, requiring minimal maintenance compared to other decorative materials. Rust-resistant coatings further ensure that these ornaments retain their luster and charm, weathering the test of time.
  • High humidity, saltwater, and constant exposure to rain can accelerate rust formation on wrought iron. On the other hand, in drier climates or indoor environments, rusting may occur at a much slower pace.

  • The tradition of using wrought iron in decorative fencing dates back to the Roman Empire, where blacksmiths forged iron into both functional and ornamental pieces. By the Middle Ages, wrought iron became widely used in Europe for gates, railings, and fences, often adorned with intricate designs that showcased the skills of the blacksmith. Each piece was unique, reflecting the style of the period and the individuality of the homeowner. This practice has continued through to modern times, where wrought iron fence ornaments are still handcrafted, blending traditional techniques with contemporary designs.


  • In addition to functionality and aesthetics, aluminium window rollers also contribute to noise reduction and improved security.
