Operating Elements for LOHSE Valves

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

Datasheet Operating Elements for LOHSE Valves


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
