(c) The spring in a safety valve or safety relief valve shall pressure which opens in proportion to the increase in pressure over the opening pressure. A

not be set for any pressure more than 5% above or below safety relief valve is a pressure relief valve characterized by rapid opening or pop action, or by

that for which the valve is marked, unless the setting is application. A pilot operated pressure relief valve is a pressure relief valve in which the major

within the spring design range established by the valve relieving device is combined with and is controlled by a self-actuated auxiliary pressure relief

assembler, and a valve data tag shall be provided that Rupture disks may be designed in several configurations, such as plain flat, prebulged or

the capacity of such a combination shall be established in to minimize the loss by leakage through the valve of valuable or of noxious or otherwise

TSV Service & Sales, a Division of TRIVACO, offers over 55 years of experience in the Industrial, Commercial and Institutional Industry as mechanical specialty sales engineers and application engineering.  As the “Factory Authorized Assembler” of Kunkle Relief Valves for the State of Indiana and western Kentucky. We provide Kunkle Safety Valves to Industrial Distributors and carry a local inventory of Kunkle Safety Valves that we can ship to you or drop ship to your customer.

Everyone is encouraged to call us and schedule a sales call to discuss our FREE survey of safety valves in your plant. This allows us to identify any relief valve installation problems and check to see if the valves are for the application and service. You will receive value from this service by addressing any potential safety issues proactively and not waiting until an unfortunate event occurs to act!

TSV also keeps record of manufacturer’s specifications for Kunkle Valve, Farris, Consolidated, Crosby and more to ensure the accuracy and quality of your valves.

We have certified our shop with The National Board and now hold the following code stamps; VR, UV, V and NB. This enables us to repair Kunkle Valve or ANY other manufacturer’s code stamped safety/relief valve, to new condition, right here in Indianapolis!

TECHNiCAL DATA pressure (bar): temperature (°c): Sample volume (ml): GENERAL APPLiCATiONS To take a sample from reactors or vessels containing: • poisoned media"s • biological media"s • corrosive media"s • environmental unfriendly media"s • liquids with high viscosities additionally the pV reactor sampling unit allows the operator to view the reaction process stage via an integrated sight glass. FEATURES • extracts a representative sample from a reactor under process conditions without stopping the process or opening the reactor. • Safe and simple operation. • Sample is transferred pressure less. • Different sample volumes are available. • ah wetted parts are pTFE, pFA, perfluor or glass. • Direct mounting of all auxiliary valves via integrated mini mounting flange. • if pH metering is required the top flange of the pV unit can be equipped with the required connection. • Unit can be connected to a continuous recirculation pump. • Unit can be integrated with vacuum, nitrogen and rinsing supply lines. • liquid product can be added to the reactor via the pV unit. • Sample media can be returned to the reactor. • No contamination of the atmosphere. Displaced air in the bottle is returned into sight glass. • Soft seated check valve prevents entering media in the vacuum line. • Unit can be flushed and rinsed in situ. • All valves can be pneumatically actuated. • numerous varieties of auxiliary valves and accessories. the unit can be integrated with various sensor devices to measure Redox, pH or temperature of the chemical process inside the reactor. www.valves.emerson.com © 2017 Emerson.

NEOTeCHA Reactor Sampling Type PV Description of operation Process Step A: All valves are closed: (3), (8), (13) and (15). Process Step B: By opening valves (3) and (8), the liquid from the reactor is lifted with vacuum through the suction hose (10) inside the dip tube through the open ball valve (8) into the sight glass (5). The PTFE hollow ball (6) floats on the rising liquid level till the ball will interrupt the vacuum on valve seat (2). This will prevent the liquid entering the vacuum line. Process Step C: As soon as the sight glass is full, the main shut off valve (8) can be closed,...

NEOTeCHA Reactor Sampling Type PV Modular conception The modular concept of the PV reactor can be tailored to virtually every customer sampling requirement. The volume of the sight glass is smaller or equal to the size of the sampling bottle to eliminate spilling by human error. 150, 250, 500 and 1000 ml samples volumes are available. We offer various solutions for heat tracing on auxiliary valves as well as to the main PV unit. The transfer device and auxiliary valves used for the vacuum or for rinsing media are available either manually or pneumatically operated. The unit can be utilized...

NEOTeCHA Reactor Sampling Type PV Rinsing and cleaning Two ports only is what it takes to completely rinse and clean the reactor sampler without dismounting any component. Connection port A allows rinsing: sight glass, transfer device, main valve and suction hose (yellow area). Connection port B allows rinsing: the area between the suction hose and dip tube (green area). Continuous flow circulation If a continuous or almost continuous metering is necessary like for instance temperature, pH or Redox metering, it is possible to equip the PV unit with a diaphragm pump, which produces a...
