The GSR 063.003811 (Type A6323/0800/7505-DT) is a 2/2-way pressure-controlled seat valve featuring a plate seal and a nominal size of 12.5 mm. It operates normally closed without pressure, requiring a delta-p of 0 bar, and handles a pressure range from 0 to 40 bar. Designed for demanding thermal conditions, this valve includes a spacer and a double PTFE cuff pack to support medium temperatures up to +300°C, with an ambient temperature range of -10°C to +60°C and a maximum viscosity of 600 mm²/s. It features 1/2 inch cylinder connections with internal threads according to ISO 228/1 on both sides. The housing is made of stainless steel 1.4408, internal parts of stainless steel 1.4301, and a metallic seal, while the drive is constructed from chemically nickel-plated brass with an FKM seal. The drive requires a control pressure of 4-10 bar using neutral or gaseous media, with at least 6 bar needed for the maximum operating pressure. It features a G1/8" pilot valve connection and can be installed with the drive horizontal or upright.
