Dembla TVAP High Performance Butterfly Valves are

available in Wafer and Lug type designs conforming to

API 609 standard. The Disc construction is Double

Offset providing excellent controllability, bubble tight

shut off, greater seat life and smooth operation. Valves

are specially designed for applications in Chemical,

Petroleum, Hydro Carbons Processing, Pulp & Paper

and HVAC industries.

Well supported shaft with heavy duty bearings ensure

perfect alignment of seat and disc for smooth and

trouble free operations. Valves have been rigorously

tested to ensure industry performance requirements.

4Valve body is solid, heavy duty. Seat

Retainer construction allows Gasket

conforming to API 609.

4Optimal disc geometry and cavity free

flow passage offers minimum flow

resistance and high Cv values.4Heavy duty pins connecting valve shaft

to disc avoids lost motion under high

torque conditions.

4Long life, easy field replaceable seat

placed in body, away from flow steam,

provides bubble tight shut off. Valves

are equally suitable for control and

tight shut off applications.

4Low friction bearings provide

maximum radial support for higher

shaft loads. The PTFE lined bearings

having low co-efficient of friction

minimizes operating torque and reduces

actuator size. They are slip in-place

type, easy for assembly and

disassembly.

4

Seat option includes PTFE, EPDM,Viton Soft Seats and Flexible Metal

Seats to suit variety of fluids and

applications.

4Recommended for critical applications

including high temperature services,

throttling steam control, liquor services,

gas applications, vacuum applications,

corrosive fluids, refinery services,

chemical services, hydrocarbon

services, etc.

Seat Design Options

Dembla TVAP offers a wide variety of seat design options which are cost-effective and

provide solutions to your service requirements. The Double Offset disc construction

minimizes the interference between seat & disc edges allowing longer seat life even

under frequent valve operations. Seats are available in both rigid & flexible construction

to suit specific requirements. The seats are held rigidly by the seat retainer which is

inserted within the body per API 609 design requirements. This construction allows use

of Gasket conforming to API 601 (ANSI 16.5) Standard and eliminate the possibility of

J OINT LEAKAGE from body to the atmosphere.

Virgin PTFE seat having a flexi lip provides bubble tight shut off in both the

directions. Suits to wide range of applications. Maximum working

Temperature 200C.

Rubber seats are available in EPDM, NBR and Viton materials. Rigid

seats allow a clean flow passage & prevents fluid deposition within the

seat. These seats are ideal for many applications in Sugar Industry Rigid

seats allows unidirectional flow (i.e. shaft side inlet) providing tight shut off

under positive & vacuum applications. With this configuration the shaftside is upstream side.

Flexible Metal

Flow from Seat Retainer Side

Flow from Shaft Side

The lip shaped PTFE Seat moves axially in

the direction of flow with the assistance of line pressure. The tightness

between seat and disc increases with increases in line pressure.

With the line pressure acting on the disc, it tries to

move towards the seat which is supported by Seat Retainer. Seat does

not move giving simple leak tight seal.

Series E and Series P actuators are powerful,

compact and durable units for use on quarter turn

applications. These are available in Double acting

and spring return versions. Various models are

available to suit a large range of torque

requirements. All actuators have mounting

flanges and drives to ISO 5211.

Piston Actuator (single / Double Acting)

Diaphragm Actuator

Actuators

Series Ldp actuators are Diaphragm operated rotary actuators using

linkage arrangement for motion transfer from linear to rotary. These

actuators are exclusively designed for Butterfly Valves and are

suitable for regulating

and on-of f applications. The actuators provide accurate, safe and

reliable valve operation at low supply pressures. Heavy-duty lever

arrangement offers great stability under high torque and shock

conditions. Low friction operation allows more accurate control, low

maintenance and long service life.

Dembla

7/30/2019 Series 7400

14/22

Series MOR Gear operators offer

simple and reliable manual positioning

of the valves. These actuators consist

of worm gear arrangement housed in a

robust cast iron housing. Sturdy design

provides long life and maintenance free

services. The high gear ratios enable

the minimum input efforts for high

torque conditions.

Gear Operator

13

Hand Lever

Series H Hand lever arrangement provides latching

system in open, closed and eight intermediate positions. A

pointer indicates the position of disc and an additional lock

facility is provided to prevent unauthorized valve

operation. Lever actuators are provided on size 2 (50mm)

to 6

(150mm) only. For size 8 (200mm) and above, Gear

Operators are recommended.
