Springless diaphragm valves
The Swagelok DE series ultra-high-purity springless diaphragm valves features a formed aluminum housing on a 1.125 in. footprint. The valve is designed for modular gas systems. Swagelok eliminated the threads that typically connect the actuator components and attach the actuator to the valve body, allowing larger-diameter pistons in the same standard footprint. The center cylinder of the actuator design provides an additional active piston to increase the force output of the actuator. The formed actuator also reduces the valve height. A smaller body in the design efficiently uses 316L VIM-VAR material. A fully contained seat design minimizes chemical and thermal swelling. Swagelok provides corner chamfers on the outlet side of the body to indicate flow direction (top view) and match actuator orientation for installation. The DE series has a high-integrity all-welded seal to atmosphere. After undergoing SC-01 ultrahigh-purity cleaning, the diaphragm is hermetically sealed in the clean room environment. Stresses are reduced on the welded seal at high flow rates. A proprietary weld isolation ring protects the weld from the cyclic actuation load of the valve. Available with pneumatic or manual actuators, the DE series can be ordered in two- or three-port configurations. The pneumatic actuator is permanently attached to the body assembly. Normally closed and normally open models have a color-coded indicator button. The manual actuator offers one-quarter turn window handle for quick actuation. The handle orientation to body is fixed for ease of installation. The valve is available in both C-seal and W-seal designs. The W-seal features a specially designed bolt retention ring that rolls down on the cylinder to keep bolts in place during assembly and reassembly. Swagelok, South Hall, Booth 1431.
