Guide Clamp

WYK / WYKS / WYPS linear guide clamps

Holding force is quoted at 0.6 MPa and is proportional to pressure within the working range. WYKS supports standard and boosted connection; WYPS adds emergency braking with a brake life above 2000 cycles.

WY36 Series

Oil cups for vacuum breakers

Suppresses opening bounce, limits opening stroke and adjusts opening speed. Rated 400 bar, 20-year design life, 80,000 cycles, maintenance-free, unchanged at any mounting angle.

Gap J

Fixed-gap throttling: simple and direct, for conventional breakers that do not need a tailored speed curve.

Multi-orifice D

Multi-orifice throttling closes hole by hole with the stroke, reducing flow area from 4 holes to 0 and bringing the piston smoothly to rest.

Adjustable K

An adjustable throttle lets you set opening speed and bounce on site, for commissioning different breaker mechanisms.

Model code

Field	Meaning	Example: WY 36 15 092 D
WY	Company code	WY
36	Outer dia. mm	36
15	Stroke mm	15
092	Stop height (nut size when limited by a nut)	092 / M36
J / D / K	Type: gap / multi-orifice / adjustable	D

Selection note:Two families depending on whether damping acts inside the opening-speed measuring window: short stroke (damping outside the window, the unit does not shape opening speed) and long stroke (damping inside the window, shaping speed and bounce). Confirm stroke and stop height against the breaker mechanism.

Accessories

The stop nut sets the effective stroke; the mounting flange is for large absorbers. Both are selected to match the absorber.
