operation and maintenance. Technical details of individual execution are specified in catalogue data sheets.
TECHNICAL DESCRIPTION AND VALVE FUNCTION
1.1 Description
Control valves RV 102 are two-way or three-way valves with threaded connection. Valve body is made of
bronze. Control valves RV 103 are two-way or three-way valves with flanged connection. Valve body is made of
grey cast iron. Flow characteristics, Kvs values and leakage are acc. to international standards.
Valves can be used as : - three-way control valve
- two-way control valve with reversing function
- two-way angular control valve
Valves RV 10x are designed for hand wheel (RV 10x R) or for electric and electrohydraulic actuators as
Siemens (RV 10x EL, HL), Sauter (RV 10x ES, HS), Johnson Controls (RV 10x EC), Honeywell (RV 10x EH),
Belimo (RV 10x EB) and Czech of producers as Ekorex+, ZPANová Paka (RV 10x ER, EN).
1.2 Application
The valves are designed for control circuits PN 16. The valves are accurately designed to regulate pressure and
flow of liquids, gases and steams without abrasive particles as water (except of drinking water ) low-pressure
steam (only RV102) and air. Sort of operating medium has to be compatible with the material body. Acidity,
resp. alkalinity of medium has to be in range from pH 4.5 to pH 9.5. For proper function the producer
recommends to install a filtr into the pipeline in front of the valve .
The valve cannot work in cavitation conditions. RV 103 valves are not suitable for steam and steam
condensate.
1.3 Function
Control Valves serie RV 10x can have equal percentage plug or linear plug. Used actuators allow 3-point
controlling. They can be equipped with the signalization of end positions and transmitters of position.
1.4 Differential pressure
Value Dp is maximum differential pressure when on-off function is always guaranteed. Recommended
max
constant pressure drop should not be higher than 0.6 MPa for valves RV 102. For valves RV 103 pressure drop
should not be higher than 0,4 MPa.

2.3 Installation of valve into pipeline
Valve must be installed into pipeline so that flow of medium is according to arrows on the body. The
actuator can be installed in any position except the position below the valve body. Keep the rules in
instalation and maintenance instructions of actuator too. Protection of actuator against the radiant heat can
be necessary in case of high temperature application. As a basic provision can be made pipeline insulation,
actuator turning aside from vertical position, etc..
For proper function of control valve, below-mentioned instructions must be obeyed :
- no excessive forces can be transfered from pipeline to valve.
- the pipeline must be cleaned from dirt before valve installation.
- the valve can not be installed just behind the bend. Pipeline should be straight min. 6xDN in front of the
valve.
- it is recommended to keep clean space around the valve for easy manipulation and service.
- installation itself must be done precisely. Pipeline flanges must be coaxial with valve flanges.
- it is necessary to use connectioned pipe union for valves with threaded connection during its installation so
that the dismantling of valve from the pipeline will be possible and can be carried out.
2.3.1 Electric actuator or electrohydraulic actuator connection
These work may be carried out by trained personnel only. It is necessary to keep all safety rules relating to
electric machines. Further it is necessary to follow instructions for installation, operation and maintenance of
electric actuators issued by the producer. Position transmitter and signalisation switches, if part of delivery, are
positioned under the actuator cover.
Before valve commissioning, the data, given in the actuator ID plate (especially supply voltage and voltage of
control signal), should be checked/compared with given specification and verify, that the actuator can be
connected to superordinate regulator.
Switching off by torque or power switch is adjusted in upper position for the valves that are equipped only with
the seat in straight way. In position when the straight way is open, the switching the actuator off is adjusted by
limit switch or torque switch with the use of the stop.
In case the actuator is dismantled from the valve body for any reason such as the valve installation into pipeline
etc., it is necessary to check the setting again after the assembly possibly to carry out the complete setting of
actuator again. Producer does not take over the guarantee if the damage was caused by improper setting or
adjusting of the actuator. In case of need, it is possible to ask for such service from service organization of the
producer.
The length of the actuator´s cables shall be selected so that the actuator can be removed from the valve without
disconnection from the terminal board.
2.3.2 Checking after installation
Piping system should be pressured after valve installation and the checked if there is not leak. Check the
packing set tightness as well. Then check the proper function of actuator by doing a few strokes.
2.4 Operating and Maintenance
2.4.1 Packing set
The packing set does not need a lot of servicing in the case that the valve has PTFE or O-ring EPDM packing
set, and also in this case gland bolt may not be tightened nor loosen. If leakage is high, the packing set must be
changed.
2.4.2 Exchange of packing set
If there is need to exchange the packing set because of high leakage, first the actuator must be dismantled and
then the packing screw must be screwed out. The pipeline may not be under pressure during changing of
packing set. After this, there is need to check the state of spindle surface and clean the inside of the packing
box. The surface of spindle must be smooth and not damaged. If necessary, the spindle must be exchanged.
Packing set is filled, by the producer, with a special lubricant acc. to the type of used packing. Such lubricant
ensures the proper function of the packing rings within their service life. The spindle may not be greased
during the operation!
After exchange of packing set, the gland bolt must be tightened to the bottom of packing box.After installation of
actuator, there is necessary to make test as in 2.3.2.
2.4.3 Exchange of plug
When the valve is used for medium with high dirt-content is probability that packing surface of plug will be wear
out and internal leakage of valve will be too high (seat - plug leakage). In this case the professional service must
be called.
Regarding the fact the valve is delivered with its actuator as a complet, the basic adjusting is carried out.
PM - 009/12/01/GB _ RV 102, 103 3/6

2.4.4 Electric actuators
Electric actuators have to be operated according to instructions given in „ Actuator manual ”. In case of
malfunction of actuator, see the instructions or ask for professional repair man.
2.5 Elimination of defects and malfunctions
If a defect is detected on the valve (leakage, leakage of packing or bonnet sealing, etc.), it is necessary to
ensure its repair immediately otherwise a permanent damage may occur to sealing surfaces and other parts
exposed to effects of leaking medium. Prior to any repair work on the valve, make sure that piping system
is free of pressure!
2.5.1 High leakage of valve
High leakage can be caused:
1 - when the valve is used under the higher differential pressure than Dpmax.
2 - by insufficient thrust of actuator. There is need to test the function of actuator again.
3 - by damaged seating faces of plug and seat. In this case the professional service must be called.
2.5.2 High leakage of packing set
In the case of high leakage of the packing set, points 2.4.1. and 2.4.2. must be done or professional service
must be called.
2.6 Spare parts
Spare parts are not part of valve delivery. They must be ordered separately. For the spare parts order, following
data must be written: type of a valve, nominal diameter DN, Serial valve´s number, name of a spare part.
2.7 Guarantee conditions
The producer does not guarantee the operation and safety of the product under conditions different from data
given in the catalogue data sheet. Any using of the valve under different conditions shall be consulted with the
producer. Defects of the valve caused by impurities in process medium shall be considered as out of guarantee
terms. The producer does not take over the guarantee if any change was made by the user without prior written
consent from the producer.
2.8 Waste disposal
Packaging and the valves (after their scrapping) shall be disposed off in the common way, e.g. by handing over
to a specialized company for a disposal (body and metal parts - metal scrap, packaging + other non-metallic
parts - communal waste).
