The Figure 234 bellows-sealed needle valve from VOG Iran offers high performance in steam lines up to 350°C thanks to its stainless-steel bellows and multi-stage sealing design, making it competitive with many European brands. Its cast or forged body typically features greater wall thickness than the market average, ensuring reliable operation up to PN40 pressure. Compared to foreign brands, the operating torque of the Figure 234 is lower, providing smoother flow adjustment. The internal stem guide effectively reduces vibration caused by pressure fluctuations, a feature not always present in some Asian models. In terms of cost, this valve is generally 20–35% more economical than European equivalents, while still supplying durable spare parts and stable after-sales service, making it a dependable choice for steam, condensate, and high-temperature fluid systems.
