385 Pneumatically operated valve with plastic actuator normally closed (NC) 587 Pneumatically operated valve with plastic actuator normally open (NO) or double acting (DA) This compact design and light weight valve has a smooth contour finish on the plastic cover to  eli- minate accumulation of dirt and is corrosion resi- stant. The actuator is designed as a maintenance free diaphragm actuator. Various accessories are available for adjustments, control and regulation which can be assembled in the factory or on the job site afterwards.

HTB ball valve Is a valve for high temperature. The primary innovation of this valve resides in the original seat design. It is not the usual metal seat but an original semi-soft soat.

Easy structures and short dimensions (acc. to DIN EN 558-1, line 16 or API 594) are the remarkable features of MVA dual plate check valves. They are to be directly mounted between DIN flanges (PN 10, PN 16 or ANSI 150). MVA dual plate check valves require a low open- ing pressure. The resulting opening power di- rects the stems against the spring and the valve’s weight power, so that the media is released. If the initial pressure is higher than the entrance pressure, the valve closes and is sealed by the O-ring to protect it from the media. Dual plate check valves do not require maintenance.

Easy structures and short dimensions are the remarkable features of MVA swing check valves. They are to be directly mounted be-tween DIN flanges (PN 6, PN 10). The swing check valves are automatically held in a central position by the flange connection screws (pos. 6). An O-ring (pos.5) seals the equipment and protects it from external effects. Therefore, we recommend to use union liners with clean seal-ing surfaces. MVA swing check valves require a low opening pressure. The resulting opening power directs the valve against the spring (op-tional, pos. 3) and the valves weight power (pos. 2), so that the media is released.
