Pump Accessories & Repair Kits

AYTC offers a comprehensive range of bypass valves, flow control valves and differential back-pressure valves that are designed specifically for Corken pumps.

Model B166B Automatic, Dual-Purpose Bypass Valves

The model B166B is a combination bypass and priming valve designed specifically for small cylinder filling pumps such as Corken’s Coro-Flo® regenerative turbine and side channel pumps. The patented vapor elimination system improves the pumping efficiency and minimizes wear by keeping the pump consistently primed. It is a smooth operating bypass with moderate to high pressure build-up and is available in 3/4" and 1" sizes.
Typical Applications: Ideal for small cylinder filling pumps and aerosol propellant feed pumps.
 
Connections: 3/4” or 1” inlet & outlet 
Differential pressure range: 25 – 225 psi (1.7 – 15.5 bar)  
Maximum working pressure: 400 psig (27.6 bar g) 
Capacity: 40 gpm (151 l/min)

Model T166 Pump Flow Control Valve

The model T166 is a moderate to high pressure build up valve with smooth-acting flow control. It offers bypass protection for pumps with capacities ranging from 30 – 100 gpm (6.8 – 22.7 m3/hr). Unlike the model B177, the model T166 modulates the flow by opening gradually as pressure builds up and bypasses the excess capacity smoothly and silently back to the supply tank. It also has a continuous internal bleed that assists in eliminating vapors.
Typical application: Commonly used with medium capacity truck and stationary pumps used to fill a wide range of tank sizes.
 
Connections: 1-1/4” or 1-1/2” inlet & outlet 
Differential pressure range: 25 – 225 psi (1.7 – 15.5 bar) 
Maximum working pressure: 400 psig (27.6 bar g) 
Capacities: up to 78 gpm (295 l/min)

B177 Differential Bypass Valves

The model B177 is low-pressure build-up bypass valve designed for applications that require protection for positive displacement pumps. It is ideal for capacities ranging from 100 to 350 gpm (22.7 to 79.5 m3/hr). It can also be used as a differential back-pressure valve that assures adequate pressure on meters. To function properly, this valve requires a pressure sensing line from the storage tank. Available in 2" and 2-1/2" sizes.
Typical Application: Used in liquefied gas bulk-plant installations utilizing loading and unloading pumps.
 
Connections: 2” or 2-1/2” inlet/outlet 
Differential pressure range: 10 – 125 psi (.7 – 8.6 bar) 
Maximum working pressure: 400 psig (27.6 bar g) 
Capacities up to 390 gpm (1,476 l/min)
Thread type: NPT or weld neck

Model ZV200 Bypass Valve

The model B177 is low-pressure build-up bypass valve designed for applications that require protection for positive displacement pumps. It is ideal for capacities ranging from 100 to 350 gpm (22.7 to 79.5 m3/hr). It can also be used as a differential back-pressure valve that assures adequate pressure on meters. To function properly, this valve requires a pressure sensing line from the storage tank. Available in 2" and 2-1/2" sizes.
Typical Application: Used in liquefied gas bulk-plant installations utilizing loading and unloading pumps.
 
Connections: 2” or 2-1/2” inlet/outlet 
Differential pressure range: 10 – 125 psi (.7 – 8.6 bar) 
Maximum working pressure: 400 psig (27.6 bar g) 
Capacities up to 390 gpm (1,476 l/min)
Thread type: NPT or weld neck

Strainer

The right-angle strainer minimizes pressure drop and is designed for liquid or vapor service. Comes complete with a ductile iron body, monel screen and steel plug.
 
Connections: 1-1/4” NPT 
Mesh: Available with liquid (14 mesh) or vapor (40 mesh) service 
Maximum working pressure: 400 psig (27.6 bar g)

Flo-Chek Valve

The Flo-Chek enables you to detect flow in the gas or liquid lines and prevents release of product from storage tank in the event of a hose failure. Flow-indicating and back-check valves feature all ductile iron construction.
 
Connections: 1-1/4” up to 4” NPT or weld flanges 
Maximum working pressure: 400 psig (27.6 bar g)
