Main groups
All LOHSE COMPACT-valves comprise the following main groups:
- valve body type
- operating elements type Hns, H, P, E, K, GK or X
All elements are interchangeable for any given size. Thereby the connections of brackets as well as the coupling of actuator and valve plate will be removed and fixed again after the exchange. No removal of incorporated valve body (notice safety rules – pipes must be pressureless).
Advantages
This facility is called the LOHSE modular system which offers the following advantages:
- simplified and less expensive holding of spare parts.
- in case of damage, actuating elements can be replaced inexpensively.
- if any valve drives have to be altered, replacement is easy and quick

Handwheels Type Hns
Handwheel with non-rising stem, left-hand trapezoidal thread. Attach a barrel handle to the handwheel of valves of type CNAHns, CBSHns and CAWHns up to DN 250.
Recommendation: for valves DN 50 – 300
Handwheels Type H
Handwheel with rising stem, left-hand trapezoidal thread, with stop sleeve.
Turn clockwise: valve „CLOSED“.
Turn anticlockwise: valve „OPEN“.
Recommendation: for valves DN 350
Pneumatic Cylinders Type P, PF and PV
Type P: pneumatic double-acting
Type PF: pneumatic single-acting (spring-closing or spring-opening)
Type PV: pneumatic double-acting with adjustable stroke in either direction of opening or closing
Electrical Actuator Type E
In principle, the valves can be operated with all conventional electrical actuators
We prefere AUMA actuators.
Chain Wheel Actuator Type K
Sprocket wheel for DIN 766 A round steel chains
rising stem
Bevel Gear Actuator Type GK
single-speed gear
speed reduction ratio i = 2:1
The actuators are operated manually
Recommendation: for valves DN 350
Square Head Actuator Type X
Square head actuator for subsurface valves
Square head DIN 3223 „C“ with non-rising stem
