Industrial fluid and application systems by Walther Systemtechnik for oils, greases (up to NLGI 3), adhesives, sealants, and 1K/2K media. From stainless-steel pressure tanks (WDBS), barrel pumps (WPS up to 360 bar), and automated degassing (WADS) through spray, chamber, and pulse valves (WSV, WDV, MPP-03) to the Walther MODULAR system and ReadyLube.
MATERIAL SUPPLY & APPLICATION · SWITZERLAND & RHINE VALLEY
Configure your fluid path end to end.
A stable dispensing, oiling, greasing, or spray process starts with bubble-free, pressure-constant material supply directly from the original container. As the Swiss partner for Walther Systemtechnik headquartered in Widnau (St. Gallen Rhine Valley), we support industrial manufacturers across Switzerland, Eastern Switzerland, and Liechtenstein along the entire process chain for 1K and 2K media – from degassing (WADS), pressure tanks (WDBS), and barrel pumps (WPS) through material pressure regulators (WMDR) to spray, chamber, and pulse valves including WVC process monitoring.

Walther Spray Valves (WSV / SMS-11 / WSDV): Universal spray valve WSV and precision spray valve SMS-11 with separately adjustable atomizing/shaping air for round and flat fan patterns, plus volumetric spray valve WSDV for metered micro-quantities up to 6,000 mm³.
Impulse & Jet Valve (MPP-03): High-frequency micro-dot pulse valve for non-contact shot application of oils and greases across distances up to 150 mm or into recessed cavities.
Volumetric Chamber Metering Valves (WDV) & Stream Valves (VMS): Piston-stroke chamber valves (0.001 to 6 cm³) independent of pressure and viscosity fluctuations, plus VMS outlet valves for bead application.
Walther Valve Controller (WVC / WVC Professional): Central Industry 4.0 controller featuring web interface, multi-parameter sets, heater control, and direct evaluation of pressure, flow (WFM), and optical light-barrier sensors (WLS).
Engineered modular manifold system built from standardized, directly connectable functional blocks. Instead of complex hose and pipe runs, material filters, material pressure regulators, shutoff and relief valves, sensors, and manifolds are combined on compact subplates into a service-friendly unit.

BEFORE YOUR INQUIRY
Ask concretely. Decide with confidence.
Which components does the Walther portfolio at dropflow cover? +
We supply the full Walther Systemtechnik portfolio: stainless-steel pressure tanks (WDBS, 2–40 L), small-volume feed systems (WKF, 1–5 kg), barrel and follower-plate pumps (WPS/WPSH for 14–180 L up to 360 bar), automated degassing stations (WADS), material pressure regulators (WMDR), spray, chamber, and pulse valves (WSV, SMS-11, WSDV, WDV, MPP-03), valve controllers (WVC Professional), flow meters (WFM), plus the Walther MODULAR manifold system and ReadyLube compact units.
When is a pressure tank (WDBS) appropriate vs. a barrel pump (WPS)? +
Pressure tanks (WDBS) are ideal for low- to medium-viscosity liquids such as oils, release agents, coatings, or free-flowing adhesives in containers up to approx. 40 liters. For high-viscosity media, pastes, and greases up to NLGI grade 3 or larger original containers (14 to 180 liter pails/drums), pneumatic piston and follower-plate pumps (WPS) combined with a material pressure regulator (WMDR) and optional degassing (WADS) ensure bubble-free, constant-pressure delivery.
Can an existing Walther MODULAR system be expanded later? +
Yes, that is the core design principle of the Walther MODULAR system. Standardized, hoseless function blocks allow existing assemblies to be expanded at any time with additional filters (WFS), material pressure regulators (WMDR), flow meters (WFM), pressure relief modules, or extra valve outlets.
Where can we get engineering advice, system sizing, and spare parts for Walther Systemtechnik in Switzerland? +
Your partner in Switzerland is dropflow GmbH, based in Widnau in the St. Gallen Rhine Valley. We support industrial manufacturers in the Rhine Valley, Eastern Switzerland, Liechtenstein, and all of Switzerland with technical sizing of complete Walther fluid systems, integration into new or existing production lines, and supply of spare parts, nozzles, seals, and expansion modules.
How can lubricant or adhesive application be monitored 100 % inline? +
Using the Walther Valve Controller (WVC Professional) combined with gear or oval flow meters (WFM), fluid pressure sensors, and optical shot verification (light barrier WLS) directly at the nozzle tip. Short shots, blockages, or trapped air (micro-cavitation) are detected in real time and reported via OK/NOK signal to the line PLC.
