Pressure Snubbers to Protect Against Pressure Surges

The PS-Snubbers series are designed to protect pressure transducers, gauges, and switches from pressure spikes, surges, and water hammer. Selectable porosity to match media.

2-Way, NO, NC, Direct Acting, Brass, Solenoid Valves

SV-3300 Series 2-way solenoid valves are direct-acting valves featuring brass, construction and FKM seal material. The temperature range from 14 to 280°F

2-Way, NO,NC, Pilot Operated, Hot Water/Steam Solenoid Valves

The SV4000 Series 2-way hot water and steam solenoid valves are internally piloted. They feature brass and 316 stainless steel construction, and PTFE seal material.

2-Way, NC, Brass & SS, General Purpose Solenoid Valves

Two-way solenoid valves for most industrial applications. It has two ports, an inlet and an outlet. A normally closed valve does not pass fluid unless it is energized.

2-Way, NO, Stainless Steel, General Purpose Solenoid Valves

The SV130 Series direct-acting solenoid valves are normally open. In a normally open valve, a plunger return spring holds the plunger away from the orifice, allowing flow.

2-Way, NC, Direct Acting, Brass, Solenoid Valves

SV-3100 Series 2-way solenoid valves are direct-acting valves featuring brass and stainless steel construction and FKM seal material.The temperature range of 14 to 280°F

2-Way, NC, Direct Acting, 316 SS, Solenoid Valves

SV3200 Series 2-way solenoid valves are direct-acting valves featuring stainless steel construction and PTFE seal material.

2-Way, NC, PILOT operated, SS, Solenoid Valves

SV170 Series 2-way, 316 SS solenoid valves have a temperature range of -14 to 280°F and the FKM O-ring make these valves ideal for many aggressive liquids and gases.

2-Way, NC, Direct Lift, Brass, Valves (Zero Differential)

The SV-3500 Series 2-way zero differential solenoid valves are internally piloted valves featuring Brass construction and NBR and PA seal material ideal for neutral media.

3 and 4-Way, NC and Universal, Brass and AL Solenoid Valves

The SV241 and SV242 can be used for liquids or gases. The most common application for these 3-way valves is the control of single-acting cylinders or spring-return actuators.

3-Way, NO, NC, Direct Acting, Brass, Solenoid Valves

The SV4100 and SV4300 Series are direct acting solenoid valves that have a brass body and a FKM seal material ideal for neutral media such as compressed air, inert gas, water

2-Way, NC, Pilot Operated, Brass, NEMA-4 Solenoid Valves

The SV281 through SV287 Series valves are 2-way, pilot-operated, anti-waterhammer, and are normally closed. These valves are designed to reduce or control waterhammer.

2-Way, NO, Pilot Operated, Anti-Waterhammer Solenoid Valves

The SV291 through SV295 Series valves are 2-way, pilot operated, anti-waterhammer, and are normally open. These valves are designed to reduce or control waterhammer

Adjustable Pressure Snubbers – Protects Instruments from Fluctuations

Protects pressure instruments against fluctuations, surges, spikes, and fluid hammer. Adjustable valve allows fine tuning harmful harmonic vibration from the fluid systems.
