VMV - ANSI Standard Bellows Seal Gate Valve
FromVMV Newton
This ANSI Standard Bellows Seal Gate Valve, crafted by VMV, is ideal for comprehensive steam and heat systems. With applications spanning hot oil, steam, and hot and cold water systems, this valve ensures superior sealing capabilities owing to its bellow seal element. This key component, fabricated from high-quality metal and attached via automatic roll welding, effectively eliminates stem leakage. The double-seal design, utilizing both bellows and packing, further strengthens its leak prevention mechanism. Supplementary features include a grease nipple for direct lubrication of the stem, nut, and sleeve, and an ergonomic hand wheel for enhanced longevity and operational ease. This valve conforms to ASME standards, including B16.34 for design, B16.10 for face-to-face dimensions, and B16.5 for flanged ends, and meets API 598 test and inspection criteria. Suitable for temperatures ranging from -196℃ to 600℃, the valve is built with durable materials like WCB, CF8, and CF8M for the body, 304 and Stellite for the seat, and various stainless steel grades for other components, ensuring reliable performance even under rigorous conditions.Most popular related searches
